Yeah, I really can't bash the concept of Android at all. I liked the widgets and all of that, but I think there was an information overload for me - too much stuff with not enough patience to deal with the quirks.
As for the "user error" comments, I followed every instruction to the T in regards to rooting, but even the experts say that there is always a chance something can mess up during root or any customization. But seriously, grow up before posting childish comments.
A few days with the iPhone 4s, and I haven't really missed any of the Android features yet. That might change in the future, but for now, I'm really happy. What I love the most is that the hardware and software work together so well. On the Thunderbolt, it always took a few reboots to get things as close to perfect as possible. There is something to be said for one company designing both the hardware and software together. I am hoping that Google will realize that, and phase out all the various device manufacturers with their custom UI's as to eliminate as much fragmentation as possible. That way, Android devices would have an edge, because if one wanted a custom UI such as Sense or Touchwiz, they could download it and install it themselves. When you buy an Android device, there is too much locked into it (unless of course you root and install a custom ROM, but as I have said, I was just not willing to do that and void my warranty).
As for customization, well as they say - there's an app for that. The apps have been very good, and they work a little different than they did with Android - less focus on widgets, more focus on notifications (which I have found work much better than they did on Android, I'm getting all my Facebook notifications). It's different, and for me, better. Your mileage may vary of course.
I'm sure I will get the chance to play with the Nexus when it comes out, and maybe I'll kick myself...or maybe I'll say that's really cool and go right back to reading stuff on my iPhone. I just happen to think that Verizon, Google, and HTC really screwed the pooch when it came to the Thunderbolt stock experience, and for me, that was the last straw.
*I forgot to add that the other great reason for me switching to an iPhone is that my entire music collection is in iTunes. As I said, I am a longtime iPod Touch user, and used to have to carry around 2 or 3 devices. Now I only need one, and don't have to worry about circumventing iTunes to get my music on my device. Just a good reason for me, again your mileage may vary.
