Really? Oh, goodie, that's great, a big hug for you!I'm already an experienced Gimper - but haven't tested Inkscape yet. What I'd LOVE to is try Krita, which hasn't got a Windows port yet.
I've never tested Krita, but it's nice as far as I've heard in Ubuntu circles. It's the image editor on Ubuntu for people who really can't handle Gimp's interface. And well, because Krita relies on so many UNIX-only other software packages and has a relatively small user base makes it not worth the effort to port it to Windows ( which is really difficult! ) to be honest. Although it's a shame for Windows users, indeed.
And by the way, just out of curiosity, what is broken in your old desktop, or how do you know it's dead? If the thing just doesn't do anything when you press the on button, it's probably just a broken power supply, which is not so hard to fix ( but you should let it be done by a computer shop if you don't know a lot about hardware, since if you do the wiring of the components to the power supply faulty, some components might blow up! ( this is no joke, a friend of mine has blown up his old floppy drive in this manner! ) ).
