With android phones coming out that are on par with the iPhone what makes you stay with the iPhone after you tried those devices? I have not moved away from iPhone yet, but the new samsung galaxy s6 has me looking into it. If you did try one of these new flagships, why did you move back to iPhone or why are you still using that particular phone, android or windows.
For me, it's Windows. My Dell Win 7 laptop is about to die (internet connection/ethernet issues) and, I was tempted to upgrade to a Windows 8.1 HP Pavilion Beats Edition


. However, after trying 8/8.1 out again (first time in almost 2 years) it did not feel viable for my already extreme expectations. I'm a teenager who likes functionality over design. 8.1 is great however, the functionality is a mess andno functional start button (use a 3rd party app)
A Metro UI for both touch screen users and non touch screen? (gets fixed in Win 10?)
Glitches and crashes (apps suposed to be opening up in desktop view but, open in Metro view and glitch out? [Happened on my test subject's XPS and, have seen many glitches on other laptops too])
Reduced battery life? (equivelent to Windows 7 models in same preformance mode.)
These are the things that turned me away and, I came to my senses and hunted down a Win 7 PRO (I have a Ultimate Disk too laying around) HP Envy which will be maxed out.
Windows is regaining control but, hopefully Windows 10 will solve all the problems. I am even debating installing the beta on a duel boot hard drive (either on my out of commisson Dell or my new HP)
This proves do your reaserch before jumping the bandwagon

Edit:
I did not choose a Mac because of there track record and my experience. I grew up with Windows (XP mainly) and, the features blew me away! Macs are different and take getting used to (I have used them before and, only find them useful for managing your iPod, iPhone or iPad ). On top of that, you can argue there durability and, especially there price tags! Thus, Macs were out of the equation for me.
One of these days, I am going to try Ubantu. It will be different but, I am up for the challenge!
