I'm probably going to wait for the "ultimate" version rumored for the 83xx series with camera and GPS. After reading about the 8300, it was enough to push me to at least try out a Blackberry but I opted to get the Pearl (which has been an AWESOME experience so far) first instead of waiting. Love the form factor and it might be difficult for me to switch back to a bigger device.
Can't wait to see what's in store for the 83xx series overall.
