I bought the new XDA2. It's much improved over the previous version. The software seems to run much smoother and faster. The only thing I wish it had is built in Wi-Fi support although I have just ordered a SD card today that will give it Wi-Fi functionality.
I need something for emails when I'm travelling. Is it capable of receiving and sending about 100 emails per day?
My only reason for not buying yet is that I am confused with the cost structure, I have no idea what I would be paying in order to send/receive 100 emails per day. (maybe it was the way the guy in the shop explained it).
