Ill have to be really honest with ya, as much as I love pdas I dont think you need one. It will be much easier just to check your email on the laptop, and much cheaper
The only reason I have an PDA is because I use the Tomtom on it. Otherwise thats it. The Wi-Fi is good on them, but I dont see the point sitting a meter away from my PC using a devise that gives me dail-ups speed when I could be using my good connection.
Thats my opinion. If you were to be getting out of the house much, I would recommend.
