Today, I reinstalled my laptop to use a fresh install of Karmic.

My laptop's one of those annoying ones that have problems, however, it seems Karmic has fixed a fair chunk of those. My wireless now works (though still only with WPA networks for some reason), I no longer have to boot with "nolapic_timer" (urgh!) and those annoying little niggles have gone. Also, Karmic is looking pretty swish. It's new notification icons are stylish and minimal, and the xsplash looks good. Also, I've noticed that shut down time is drastically reduced! (2 seconds vs my old 10-15 seconds).
Boot time isn't amazing, but it's pretty nippy.

I'm lovin it.
