If you have fingernails the i phone might be tough to use.
I have a hard time using DHs & I don't have very long nails.
After a day or two nails aren't really an issue.
As for which to get, dh & I got iphones earlier this month. He had blackberry before. He says hands down the iphone is the best device ever. And trust me, if it's been out he's had it. He says it's much easier (and faster) to pull up (and find) information on the iphone.
