Yeah! XP rocks on my new lappy at work. Although, you must pay careful attention on how you install drivers. Here's the story (as though anyone cares...)
Dell Inspiron 4100 Lappy w/DVD drive, WinXP Home. Everything works out of the Dell box. Woot! Put it on desk and plug HP 940c printer into USB port. XP sees printer, installs it's own drivers, printer works fine. I go to install the HP supplied Win XP drivers via the DVD drive. WinXP never sees disc. Any disc. Sees the drive just fine, but no media. Hmmm. Interesting. Anyway, I uninstall printer drivers, reboot lappy (with printer unhooked) and DVD works again! Cool. So I put the HP XP driver disc in drive, start the install, connect printer when it tells me to (though I have the printer plugged into the wall outlet) As soon as the USB plug is in lappy, WinXP installs it's own drivers and the DVD doesn't work again! Printer MUST be unplugged until the driver install program tells you to plug it in thus preventing XP from installing it's own drivers. Nowhere in any documentation does it say anything about this. I have posted the the Dell forum so noone else has the fun I've had.
Anyway, yeah. XP rocks. I like it bunches.
