Not particularly impressed with Kubuntu Feisty so far.

After one and a half days of use:

• one major – unrecoverable – crash in X (i.e. couldn’t even get to the console using CTRL+ALT+F[n])
• Playing with “Monitor & Display” setup in System Settings resulted in an un-useable X configuration — okay not actually Feisty’s fault, but I’m disappointed it still doesn’t work in this release — thank god for a backed up, working xorg.conf.
• OpenOffice, usplash, skype and a couple of other apps that temporarily escape my memory, have all crashed at one point during the day

So initial experience is indicating stability is significantly worse than Edgy. It’ll be interesting to see if it improves over the next few weeks/months…
