Speaking only for myself, and I am unanimous in this, it's the BlackBerry 8700 for me, all the way. I started out with a BB 950 (sold by AOL as the AOL Mobile Communicator). When AOL shut that service off a little over 2 years ago, they offered me a $100 discount on a T-Mobile Color Sidekick if I switched to that, so I did. After a year-and-a-half of unreliable, bug-ridden service, I dumped it in favor of a BlackBerry 7520 and haven't looked back. The BBs have caught up to, and surpassed the Sidekick in terms of the features I look for, and the difference in reliability, durability, and security of my data is night & day. The BlackBerry puts the Sidekick to SHAME!

If the Trēo 650 is even HALF as unreliable, even half as flimsily built as the Color Sidekick, it'd only make me mad as hell!

So, I'm sticking with what has worked best for me... my beloved "CrackBerry"!
