I promised something more intuitive than Mac, and that thing is Linux. If you have passed the stage of computer use bordering on complete ineptitude maybe its time to take off your white plastic training wheels and admit that you know what an executable is, and how many mega's fit in a giga. Step up to GNOME or KDE, pick a flavour.
Many Mac fans will argue that Vista is a clear attempt by Micro$oft to be more like Mac, I won't argue this, it's really obvious. And many PC users argue that Mac is trying to be more PC, and admit it, Pentium? Exchangeable hardware? Kinda smells like a PC in here. But let's take it back a step.

Holy Keokuk, was that Windows? No, I think it may have been Mac OS. Or was it, possibly? GNOME? An old version of GNOME? Hmmm, looks kinda familiar. GNOME, and indeed every major flavour (isn't that trendy? They call them "Flavours" is Mac STILL stuck on "Versions"?) of Linux has a sleek, stream lined user interface, with near limitless customization (Have I got the designers attention yet?) and visual options.
And you want "It just works"? How about the most stable operating system to date. Has your Mac ever crashed? I mean ever, even once? Linux can recover from a crash without restarting, because of its structure it has a kind of super-powered Task Manager. This means the most stable operating system to date can't even be slowed down by anything short of a power outage. Or intense system manipulation by trained programmers, which is what it was originally designed for.
So in both the "Interface made for designers" and the "It just works" fields Linux wins. And guess what, you can install it on the m15x from last post. Now THAT is a good designer's computer.
