Switched from the Droid 2 and got my phone yesterday. I do miss the notifications, but it is not a deal breaker. I also read there was an App that makes notifications more andriod-like but I havent gone looking for it. The facebook widget was nice for one-click status updates, but other than that did not use widgets much.
A native app which allows you to one-click dials or texts to a certain person would be good, the Droid had that. I found an app "You" which works okay, except you don't know who "You" is on your home screen.
Another Facebook note, in my Droid I could upload a photo to facebook/twitter/ect directly from the gallery. I don't see "share to facebook" as an option on the iPhone. I created a shortcut of my own however because now facebook allows you to upload pictures to your wall via email, which you can do via the iPhoto libarary. Anyone out there know if there is an app for that???
Other than that: HUGE PRO: TYPING! I couldnt send a single text message on my droid without a typo because of my fat fingers, and now I can send a text one-handed typo-free....YES! Isn't that the way its supposed to be?
I gotta say the hardware and the screen are beautiful, makes the Droid look like couple of tin cans slapped together!
I have been an Apple fan for life, so couldn't wait for this day....there is an adjustment period but I am verry happy so far!
