Originally a Crackberry Addict for about forever, then changed to a Atrix 4-Android last February when they first were available, but switched to the Iphone 4s a couple weeks ago because of several reasons.
First, didn't like the Motorblur on the Atrix 4.
Second, the speaker was inadequate and the quality was below average.
Third, I felt the phone itself was outdated within 6 months of purchase, with all the new phones being introduced with the Android platform, and also the software updates were uninspiring.
I love the display, the platform, the software, the apps, and really love the ability to sync my Ipad with the Iphone. Makes my life a lot easier.
