Well, I've been playing with Ubuntu 6.06 for a few days, and I will persist, but it isn't all that simple to a child of the windows generation -I started with Amiga computers- but I have found:

Everything has a different name, you have to keep looking things up

Firefox browser is very clunky. the pionter moves jerkily. When you scroll down, it keeps scrolling (slooowly) to the amount that you moved the wheel, which is probably further than you wanted to go, so you have to scroll back up, and you go too far again, so....
Opera works much more smoothly on Ubuntu, and Firefox works much more smoothly on XP. Same computer.

Your printer may not have a driver, and if it has, it may not automatically unpack and install. Command lines.

You have to type in two identifications every time you boot. Irritating.

There are good websites, though. But they are not as easy to navigate as this one.

I downloaded the latest version. 4.75 hours. Now if only I can work out how to load it! Seems I'll have to make a boot-disk, if I manage to understand the language.
