As some of you might know already I bought a new laptop recently. My choice was the Samsung X20. And what was the first I did with it? Put Debian on it. Currently it runs Sarge using the 2.6.8 kernel build by nobse (I think, at least ;-> )
Samsung tells me it may run up to 5 hours unwired, but (using Linux) my acpi tells me something about 2:20h after unplugging it from power with a full battery. I did not check up to know if it's estimate is accurate, I'll tell you so if/when I've done.
Linux works pretty nice on it, there are plenty of howtos/tutorials out there on the net. Thanks to tokkee for helping me with the IPW2200 to get wlan up and running. The things I didn't check up to now are the card reader, firewire, the external screen/beamer connector, as well as composite tv and the S/PDIF auido features.
One point why I decided for this X20 is the graphics card is an ATI X600, which has its own memory and doesn't steal me RAM (which is actually 1GB). It gets pretty funny when starting glxgears after activating the OpenGLOverlay option in the X-config: it goes nuts and tells me something about avg. 2300 FPS... %-)
