My dad was forced to get a BlackBerry for work and he hates it with all his heart and soul.
My mom had a Droid X and it had a lot of glitches. She liked it but it kept on breaking down on her (and she did switch phones, she didn’t use the same one the whole time). Also, my dad has an iPod Touch and she couldn’t use the same apps as him. Then she got an iPhone 4S and she’s in heaven.
2scents: that’s what my dad does. He has an iPad and a regular old (and yes I mean old) phone. And an iPod Touch but it’s kinda broken. He says he doesn’t want to put all his eggs in one basket. (I don’t count the BlackBerry because he doesn’t use it unless he absolutely has to.)
Personally I’d take any of them :).
