windows os is cool not as hardware hungry as android its seriously a ios alternative at a low cost, its fast fluid and good for multitasking, just a few years and it will overtake android, google is also frighten about windows os thus is reluctant to develop its software based services for windows phone os like chrome,gmail,maps apps.
Some of the new features are good but still lacking Android functionality, eg. 3rd-party keyboard - still no arrow keys (at
least left and right) to navigate and correct mistakes while typing, which I find very useful personally.
It really boils down to a single question:
Can they make profit with Windows 10 phone?
Really great news xiaomi also releasing WP 10 in china. Hope they make good wp devices.
Now it's the time to bye android and to buy window .future is of window and it will write by window 10
