With a Blackberry you have to keep the data package on your account. It will cost you $29.99 per month on top of your voice package. Blackberry's are nice, but if you don't do business or don't really get a ton of emails, they are overkill. If you get a windows or palm based
pda then you don't need to put the data package on, but you wouldn't want to use data at all. The data packages on those are $44.99 per month. One advantage is Blackberrys push the emails right to your device, where the
PDA's have to be set to go out and retrieve your emails. You can do instant push, but thats more for business people again.
