It'd be great if PPCT can do a roundup of all of these against Pocket PC and GB Advance (though one of them will run Palm OS)...
P.S. I played Snails on my 2210 all during my dentist visit, the doctor, interns, etc were amused and interested. 'twas a protection mechanism to soothe my fears though (once I hear that drill sound I break out in a cold sweat)...
