I'm using a Dell i8100 (1.2 ghz P3-M), my experiences are similar to Ico's except the soundcard input in mine is pretty bad, and the spdif doesn't work. I can (or could, when they were new) get about 10 hours out of the batteries. Its my main development machine as it has a great keyboard and screen. The screen is better than anything I've seen on a desktop. OTOH its so heavy that I had to stop carrying it home every evening cos it hurt my back. I've used WLAN cards in it with no problems, but the current Planet CCRMA kernel doesn't have drivers for my card so it isn't working at the moment. There are drivers for everything else though, including the graphics card. - Steve
