Not that I have anything else to do this morning, I installed When on Virtual Box, was unhappy with it and tried again with VM Workstation. Much better performance, mouse less sluggish.
But it caused me to think about the wonders and possibilities of using VMs to protect onself from catastrophe. I'm a consultant, and I image my main working laptop drive weekly. I cannot afford the time to re-install all of my software. But playing with VMs this weekend - suggests just using a VM to begin with, keep all work in container files and let the native OS just be a very limited native OS.
How many of you follow this approach? The performance seems acceptable, especially on my Xp VM.
I use Win 7 Pro 64bit day to day. Thought I might have to re-install everything into the new VM, but no, vmware provides a nifty utility to just pull it in to the new container.

I do use - extensively - VMs...(Virtual Box actually  )...
I have a host OS (Fedora) that is very limited in usage (e-mail and browsing), for anything else I have VM - SQL, Visual Studio and so on. I turn on and off those VMs as I wish and as I need...
The best part is when updating hardware - host OS is up and running in 2 hours max, from there to 'install' other OSs is a simple copy-paste with a minute of re-connecting them to Virtual Box...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

I tried this a couple years ago and found the mouse and keyboard delay to be just a tad too noticeable and thus rather annoying. I haven't tried it since I upgraded my machine to an 8 core 16GB all SSD system, except that I have to run Ubuntu in a VM (using Oracle's Virtual Box.) There's still the "mouse just isn't snappy enough" but then again, I detest the UI that Ubuntu comes with. Whoever thought that a window's scrollbar should be hidden, requiring precise hovering over just those few pixels on the edge of the window so that the scrollbar pops up, and then it's this ridiculous slider thing, well, that person should be banned from UI design.
But I digress -- I do indeed completely agree with your point, but whenever I've set one up, I seem to never use it, mainly due to lack of discipline.
And then I get into the scenario of, oh, I need a custom control, let's download the code from this article, nope, not quite what I had in mind, let's try this one, etc., or even worse, doing that with third party software, and I'm not disciplined enough to do it on the main OS, so I end up polluting the VM instead. Of course, I could have saved an image before trying a bunch of options, but again, that's a discipline.
I figure I might try this again and, having failed at this a couple times and learned valuable lessons regarding the care and feeding of one's VM, put those lessons into practice. Discipline!
I should try VMWare again as well. The Virtual Box / Ubuntu combination pisses me off because copy and paste between main OS and Ubuntu doesn't work on one VM I use, but does on the other (probably because one is 64 bit Ubuntu and other is 32 bit Ubuntu) but copy and paste is essential because of klunky the tools are in Ubuntu.
That said, the other thing that I find really helpful is the ability to network into the VM from the main OS -- I would definitely recommend that, either mapping a drive to the VM (for Windows VM's) or WinSCP'ing into the OS (for *nix OS's, PuTTY is also your friend in that case.) It's a huge timesaver to have your VM open but be able to access files from your main OS.
And lastly, put everything valuable under source control, which is a great way to sync between the main and VM OS's. Which of course requires a private repository for private stuff. Options like DropBox, GDrive, etc., suck IMO, for my work process (too slow to sync, added bloat-ware running in the background, etc.) and furthermore, I don't trust that Microsoft or Google isn't looking at my stuff or that we'll read some day about some massive DropBox security breach.
So, long post, hopefully some helpful pointers from lessons I've learned.

+1 ... that's one of the reasons I prefer other desktops over Ubuntu's Unity ... and thus use Kubuntu instead (i.e. KDE desktop pre-packaged into Ubuntu without any Unity / Gnome stuff).
As for the sluggish mouse ... don't know ... wasn't that way for me: Kubuntu 64 host OS, VirtualBox with Wen 64 as client OS. Mouse worked seamlessly - just unfortunate that VB's drivers hasn't been updated for Wen (yet), thus 3d programs were less than acceptable while they work reasonably in a client W7 (not great but not causing hair pulling).

Just to advise: I like KDE not because of its looks but more because it's so damned customizable. Actually it looks like what W8 should've been as an upgrade of W7's UI.
If that one's not for you, there are various other desktops available for Ubuntu. From Gnome 2 or 3, through Lxde (like a very light weight XP) or Xfce (light-weight OSX lookalike if you customize it a bit) through to several others: http://www.howtogeek.com/163154/linux-users-have-a-choice-8-linux-desktop-environments/[^]
You also don't need to uninstall Ubuntu to try out another desktop. You can install a new desktop from the Software Centre and then should have an option in the login screen. I just don't like wasting several megs of my SSD on something I'll never use.

Ah, wonderful. I was wondering about that, did a little research already and didn't really want to create a new VM.
I've used Lxde with the Beaglebone, it's definitely really nice to have different desktop choices, it's something I wish Windows provided.

I've switched to using VMs pretty much exclusively years ago and haven't looked back.
My VM host (one of the first i7 CPUs of the Sandybridge generation) has, quite literally, nothing installed on it, except for some motherboard drivers and TrueCrypt (the external drive I back up the VMs to is encrypted). I don't bother backing up the physical machine's OS as it can be reinstalled from scratch and running well within half an hour.
The VMs are on a separate physical drive (well, a RAID array in my case, but any drive will do). If something bad happens and I have to replace some hardware, none of the VMs are impacted in any meaningful way--the worse I've seen is that I've had to reactivate some Windows instances. I had to replace the motherboard at one point; earlier this summer, I moved from Server 2008 R2 to Server 2012 R2. In both instances, I just reinstalled the OS, the drivers, and any available update. I recreated the VMs (specify how many CPU cores, how much RAM, etc), and pointed them to the existing VHDs on the RAID, and they're all back up and running. I know you can backup those VM definitions from somewhere, but it's so quick to re-do that from nothing I've never looked into it.
The machine is physically located in another room in the house. I RDP into the VMs from the rather modest system I have sitting on my desk; its most notable feature is that it's hooked up to three monitors; there's otherwise nothing special about it. It also hardly has anything installed on it, as I spend my days in RDP. I can access any of these VMs from a desktop system, a laptop, heck anything that supports the RDP protocol like a tablet running Windows or Android (I know MS also has a client available for the iFruits, but I don't own any). Point is, I can access my fully functional machines from any number of devices.
I have a separate VM for every version of Visual Studio from 2005 to 2013. Most are always powered off, but ready to go at a moment's notice. If I need a clean IIS or SQL instance with nothing else, it gets its own VM. I have one VM dedicated to testing crapware I'm not familiar with and might not necessarily trust yet--that goes a long way to keeping your everyday machine(s) in a pristine state. I have VMs for testing my apps against all of the older Windows versions I care to support, and a few Linux distributions just to tinker with (I'm not heavy into Linux, but most of the popular ones I've used work without a hitch on Hyper-V).
Backups are simply done with a script invoking robocopy.exe, which is smart enough to skip over VMs that haven't been powered on since the last backup was done.
I have clean VHD files with nothing installed on them except for the OS (from 2000 to this week's Windows 10 Technical Preview). Getting a new VM up and running is just a matter of copying a VHD file to the "live" VM drive, specifying how much RAM I want to give it, renaming the machine once it's up, and it's pretty much good to go.
IMO, as a developer who's spent way too much time doing IT tasks and rebuilding machines from scratch before virtualization became mainstream, there's just no other way to work.

Okay, gerbils like IE on Windows 7. IE on When always results in chattering from gerbils.
How do you handle all of the licensing for your different machines? Windows of course, but it smells like you have MSDN or something.

Yeah, I have an MSDN license. I believe MSDN gives you some additional leeway as a developer in how you use the software you have access to. In that sense, I don't think of any of my VMs any differently than I would for physical machines.

Very impressive. I like your idea of RDP'ing into the VM's.

As you wrote in your original post, it all comes down to discipline. Once I got the hang of it and stuck with my own set of best practices, everything became a no-brainer.
One warning though--spinning up new VMs for different purposes quickly becomes a habit...I original bought that machine with 8GB of RAM, then quickly moved on to 16, then 32, and I'm now wishing that it could handle 64 (this is all consumer grade, off-the-shelf hardware).

The windows world is pretty far behind on that front. With Linux there is vagrant[^] to make managing virtual machines much easier. I'm just starting to get up to speed on it.
For application deployment, there is docker[^], where you can virtualize just the files and apis for a specific application. I haven't started looking into it, just reading up on it right now.
It looks like vagrant added support for windows guest oses with the latest version. https://www.vagrantup.com/blog/feature-preview-vagrant-1-6-windows.html[^]

Vagrant runs on Windows as well (I have it installed, just haven't worked with it yet.) It looks quite cool, and is written in Ruby.

I used a vagrant setup by a coworker to create an Unbuntu VM to host a rails project I worked on earlier in the year. Other than some startup snafus (mostly caused by a default changing between when my coworker learned it and I installed it for that project) it worked great. Much easier than my trying to config a VM by hand would've been.

It's a very good approach.
I use a virtual machine for Linux building, with the mass of environment variables set up months ago.
It lives on a Windows 7 machine and enables me to exploit limited resources(KVM switches and desk space being rare and costly)with a couple of clicks.
It also allows me to tweak the build environment without breaking any other projects I have on the go.
And of course, imaging the the master file makes it disaster proof.
