I just got the blackberry storm 2 days ago after my Samsung PDA Of 3 years decided it doesn't want to serve me anymore. Despite the not-so-hot reviews users gave it on amazon and other sites, I love mine!
I think that since I got used to using a touchscreen I didn't find this blackberry non-user-friendly which is what most people say about it, I definitely didn't want to go back to pressing buttons but if that's what you're used to than you might not like it. The free applications are useful, the screen is really clear, the keyboard buttons and icons are big enough for me, and I found that it's very easy and convenient to check and send emails. I've heard the iphone is a lot easier to navigate; I don't have too much experience with the iphone so I can't comment there. All I know is that I'm more than satisfied with my selection!
Ok I have to admit it wasn't complete smooth sailing, I've been unable to send text messages but that's actually more of a verizon network problem than it is a blackberry problem. Also general web browsing is slow and probably not too practical to use, but that's the case with the iphone as well. Hopefully I won't be getting too distracted in class!
