Up until 6 months ago, I felt the same way about wanting my phone to be "just a phone".... then I got a Crackberry.
As a Phone, I will honestly say that it's the best sounding cell phone I've ever heard, and the speakerphone works quite well. It communicated to MS Outlook and syncs your address book & contacts. I also get e-mail on it (from two different accounts) and has a 2-way radio feature that I use often, as many of my clients use them as well - honestly the best thing I could have ever done to communicate with the outside world (although, I could do without the sms-speak....) I know several people that run their entire small business with one.
I always thought that I didn't want, need for want to shell out the coin for the pricy phone plus the expensive data service plan. Now I can communicate better and faster with my clients - and it's paid for itself many times over.
The only real problem with it? Once someone knows you have one and you
don't respond to an e-mail in 60 seconds flat, they feel ignored (I know someone that received an e-mail from a client at 8:30am, then again at 8:35, 8:36, 8:37 and 8:40. at 8:45am they got an e-mail saying that they "must not want their business" and he lost the contract
...anyone else out their hooked on the 'berry?
