Any Hardware issues? Esp. video issues. I've got the same video card as you do and was planning on going with Madrake 10. Were things like the networking annoying to set up? I know on my Dell I8000, they were a serious pain due to a slight bug in the pcmcia module.
What I'm really worried about is damaging the screen, since I couldn't get AW to let me buy a warranty.
I have my Sentia dual boot XP and slackware 10 as well.
Slackware is running Dropline Gnome. Sound is working fine except for DVD playback for some reason that is off and on. Wireless I have not tried, but will probably try the widows driver wrapper instead of waiting for the Intel 2100 Linux drivers to get past beta.
