i use the C3000 with the keyboard. the keys are plastic with about 1/32 inch travel depending on the sponginess of your fingertips they make a positive click when fully depressed. the trouble is typing with more than 2 fingers you can't get them close enough. also if you have to deal with 5 different keyboard layouts between the 3000, pda thumb board, smartphone T9 and qwerty desktop and laptop. you can get a little confused which key combo to use by memory... all in all in make a great belly-top computer for the couch potatoes, and it's super on the plane, or crowded board room you have plenty of desktop space left over i also recommend getting the screen protector, and the leather case. they make excellent additions. the only problem i'm had was loosing the stylus so soon, i've never lost one before!
