Well, the upgrade from Kubuntu 8.04.1 LTS to 8.10 was fairly painless. I’ve lost the Eee OSD and ACPI script fixes I applied, and the installer rather helpfully removed the Array.org kernel, so I can’t use the WiFi on my Eee 1000H any more. Those are easy to fix, though.
KDE4.1 is… well… awful. It’s redlining the CPU and thrashing the HDD quite badly (on a 1.6GHz Intel Atom N270 with 2GB RAM no less). The UI is slow. Slow, slow, slow, slow, SLOW! I though the Vista beta in VMware Server was bad, but this takes the biscuit!
I like (some of) the eye-candy, but the plasmoids are completely over the top, and the random graphics glitches are awful.
Four and a half minutes from entering my password to actually being able to start an application.. Ugh.
