Ordered a 650 yesterday off amazon.in for just under INR 14k (launch price was 16.5k in April) so should get it by tomorrow! Already got a 550 a few months ago which my mom uses and it works pretty well for a low end phone.
I already use an iPhone 6 as my primary phone mainly because I had no choice for my work phone and while it's pretty good, not really liking it too much.
Main reason for getting the 650 is now that W10M version 1607 build 14393 (anniversay update) is around the corner and for running RS2 when some new features start to come out in a few weeks/months!
Looking forward to the OLED screen and its wider 4G band support mainly. I don't use camera much and didn't feel the need to spend double the money for a 950 and it's additional specs (CPU/RAM/storage) which I would hardly use like Windows Hello, nor do I do games on it.
Might miss DTTW though if it doesn't come on this device.
