Ok, true 7210's keypad is wierd. But I haven't tried the3200.
Worst yet was the 3650. I'm telling you it was a living hell, especially for typing messages, it was so darn difficult, that i altoghther gave up, and settled for a traditional keypad layout(and eventually got a 6610, C100). I would have surely got a 6600, as there are no probs with the keypad but now, my purchase is over!
