That would be me - though you can just lurk in the ubuntu forums.
I have some
notes. In fact, it's about time I updated that page because the issues have been solved.
I'm running this distro on a custom desktop: asus p5p-vm + i4300 1.8GHz, 128GigHDD and 1024MiB DDR, nv6800 agp. It is very very sweet on this system, which is hardly high-spec these days.
Also installed to 4x hp/compaq nx5000 laptops and eerything working out of the box except for the wireless LED - which was a one liner, and not a bug. These things are four years old, fully intel, and grunty enough for the full distro, including compiz/fusion with all the trimmings.
Those are the boxes in my possession. I have seen a couple of ubuntu installs fail.
I have a range of experience with different distros - Ubuntu is kindof a default. If you want to play, try an experimental distro. Something built with a specific aim in mind.
Yoper is fun just for the speed.
Sabayon is very pretty.
Minimal distros can be very cool and easy to customize. I had fun awhile ago with Zenwalk+Enlightenment ... a nice combination of names. But DR17 was too unstable back then.
And, of course, there's linux from scratch.
