Im still using 6.06 and don't plan an update for 07 and 08.
I need a stable OS, which I got, and didn't risk anything, and installed Java myself without apt/dpkg knowing of java, because I like to decide myself, when to update Java - more often or less often, than the supporters think about. And installing java by hand is not a big issue, while I don't know enough about the deb-System. Of course I need java-1.4, 1.5 and 1.6 in parallel.
The second package without ubuntu-control is eclipse. And that's it.
Well - perhaps 2008 with a new Laptop.
Ha, ha - having said that, I look at my bittorrent-window, which indicates: ubuntu-7.04-server-i386.iso 100% complet, 290 M up. I will install it on a rarely used desktop.
