I'm jealous of that 8830. I've been considering a switch to a BlackBerry from my RAZR for a while, but it has also been dependent on me buying an Eee PC or not. But now that I've got to buy a car, that may have to be put on hold too...
We'll see. My first opportunity to trade-in comes next month, I may just go with the Palm Centro.
I'd assume your service is with Sprint right? When you say first opportunity do you mean for the $75 off or the full $150?
In my personal opinion, I'd pass on the Centro. The price point on it is great, it's not a bad overall device. But the phone is very tiny, the keys are even smaller (meaning it's a pain in the ass to type on), bad stylus, and it just feels cheap because of the materials they used to build it. Not to mention Palm's aging OS that we're all waiting for them to get rid of since they've been working on it for who knows how long.
The Blackberry speaks for itself, it's a wonderful device. I can't say I've had a single problem with it. If you're kinda putting off buying a new phone until later, there is a CDMA version of the Curve that will be carried by Sprint this year supposedly. There's already test handsets out which generally means that the actual device launch is a few months off. So that will throw another option in there for you.
