Re: would you go back to any other phone?
My experience with Android wasn't as good as what I hoped. Part of the reason why is because I am tied to the Microsoft Ecosystem. I didn't like how Microsoft didn't fix the outlook app for syncing with Outlook.com.
#1. Contacts were a one way sync, with no editing on the phone
#2. I set up outlook.com as an EAS account and the calendar didn't sync correctly. I have several calendars I use for work and personal. (Birthday, work, home, bills calendar)
#3. My LG G2 become laggy after just a little bit of time, I did a hard reset and it fixed the problem but it came back
#4. Battery life wasn't as good as expected, I got much better battery life with the same thing turned on with my Lumia 920 and my iPhone 5s.
I just used T-Mobile jump! to get a iPhone 5s, I like the phone, email, contacts and calendar work flawlessly, and the only thing I don't like is the small screen. I loved my Lumia 920 but MS isnt' releasing any top of the line Windows PHones on Tmobile anytime soon so I went with an iPhone (at least for the next 6 months).
Both experiences with Android (2009 and the last 6 months) haven't been positive, thou this time was much more than the mytouch I had in 2009. If Microsoft can not only get more apps, but freaken have better app quality I would go back in a heart beat. Facebook still hasn't hasn't made an app for Windows Phone and the one by Microsoft is surely lacking.
