I'm curious about something and could use somebody's help. I published a windows phone game app to the marketplace yesterday and was curious about how long it takes before it is published/available in other countries. If you don't mind, and you have a windows phone 7 and or windows phone 8, please go to the (non-US) marketplace and see if "WhichWay" is available and let me know?
I have HTC M8 and its good in many aspects. But I am not sure, you have models with your budget constraint. The models I suggested are running Android ASOP which has more options for customization where customizing the phones, it complex.
But take a look on the latest HTC Desire series & Eye if you are leaning towards HTC.
Nexus 5 is done and dusted, although I am a proud owner of one and it is the best phone I have ever bought. Once a nexus user will always be a nexus user. One plus one is too big a thing to hold IMO. HTC desire eye is a very good phone and has a good look and form factor. I dont like the one series atleast according to me they are ugly elder brothers of desire series.
Nexus 5 is pull off from the Play Store. But you still can get in eBay or Flipkart. I never had One Plus, but its running on CyanogenMod which will be easy for users who want to try rooting and flashing custom roms. I don't agree with your assumption about One Series and Desire series or not even close to them to compare.
About nexus 5, you are briefing what I summarised. You can get in flipkart or whatever but the price is likely to go higher, and the chapter is closed officially anyways. About one plus one your point is correct but its size makes it disadvatageous, not everyone's cup of tea. I have rooted my s3 with cyanogenmod and become a fan of it so I totally agree with you in terms of software. With respect to HTC it was my personal opinion and I will never buy a one series until they replace the ugly speaker grills until m8 with desire one style. M9 does better job in this regard though.
