My DH has one from work and can't stand the thing and has been complaining about how terrible it is for a long while now. I wish I could tell you all the complaints but the list is long and I really didn't listen all that well. Anyhow, for Christmas he wanted an I-Phone very badly so he got one and still totally loves the thing. Personally, I think they are both overkill. I mean, who really needs e-mail 24/7.... if it's personal either text or call, if it's business turn it off and live a little. Sure the internet stuff & apps are cool, but I don't think he really NEEDS all that stuff, and I don't see the want being worth the expense but that's just me & my opinion. As long as he's smiling I keep my mouth zipped, it's a fair exchange for him not complaining about my WDW addiction.
If you really want it and can afford it get it, but if you'd struggle for it then I'd skip it.
