I have dabbled

Have Mandrake 10 installed on a drive at the moment.
Only trouble is, as soon as I run into a problem and I can't fix it, I lose patience, get frustrated and give up. It really is quite a long learning curve, imo, and that's just Mandrake, supposedly one of the most user-friendly distros.
Mandrake 10.1 official will be available for d/l in a few weeks, I'm going to get that and make a serious effort this time at learning this thing.
One disadvantage with having a dual boot system is that if either OS decides to hose the mbr, it's possible you won't be able to boot into either. I suppose you could say that with any OS, single or dual boot, but I've managed to do just that with an installation of Red Hat and XP a while ago. Twas 'format C:' time
And Quad, yes, I'd agree, browsing does seem quicker to me within Mandrake than within XP.
