So far so good, it's got to be said! There's a few issues I've noticed though, these are:

1. gvfs-trash errored out on first boot, doesn't seem to work
2. gnome-power-manager did the same
3. Shutdown from the shutdown menu doesn't work
4. Keyboard shortcuts don't work

Now I can't really comment on the first 2 because I just sent off the error reports and then I got no more prompts...or running applications Though shutdown is an odd one, I have the button on the far right of my top panel, and under the system menu. Trying to shutdown or restart from either doesn't work at all. I hope this gets fixed soon, until then I may added a launcher to my panel to shutdown instead;)

Keyboard shortcuts is a pain, I have a keyboard shortcut for the terminal, but it doesn't work So I tried changing it to a different key combo - still no dice. It's a shame, it's only now that I've realised how much I used it. I hope this also gets fixed really soon, so I can remove the terminal icon from my top panel.

Other than that I'm really enjoying the Intrepid Experience so far. The "newhuman" theme has grown on me quite a bit. I actually quite like it now, I was unsure at first. Also Compiz works great (cube deformation & 3d windows have been added to my features). On Ubuntu 8.04 running 3d Windows made my laptop grind to a halt...smooth as anything now I'm happy!

I'll post more thoughts after Alpha 5, Beta & RC etc. Until then - have a screenshot or 2

UPDATE: Thanks to this comment I managed to get my terminal shortcut back - so thanks for that I still think that'd be classed as a bug though.
