With WM5 and AKU2, the Windows devices do a great job of real-time email. I'm using a Qtek 8310 that will use Wifi for email when it can, otherwise falling back to EDGE. The whole thing is seamless as can be. I'm excited to try the UMTS version, though.

I see that TigerDirect is selling unlocked Blackberrys for $99, no rebate needed.
