what I use

Hooray, some linux!
My main system is a dell desktop 2Gb Ram, Celeron 2Mhz, 500Gb & 250Gb disks running Hardy.
Also Laptop HP running XP for family 2Ghz Pentium 2Gb ram 80Gb disk.
Both connected to Dlink wireless and also 100Mb ethernet.
Also, 2 Compaq deskpro 933 Mhz 256Mb ram. One has 500Gb running knoppix and is just for backups. Other is a spare for trying stuff!
Have been running Hardy for a year now and looking for something to upgrade to but can't find anything as stable yet. Have Jaunty in virtualbox (missed Intrepid) but akregator keeps crashing.
EXT4 looks promising though.
Bye the way, I tend to use KDE so it is that flavour of (K)ubuntu.

let me know if you find a stable (kde 4 preferably) linux. I am trying various flavours in Virtualbox.
I will pass on my opinions in a further post.
