I have the same 1024x600 screen on my EeePC, and Evolution's preference window is too big for the screen. My solution? Switched to Thunderbird. I'm also using Easy Peasy instead of the default Asus Xandros distro.

Inkscape kicks ass, though.

GIMP doesn't have the features. When it does, people will stop complaining about it. Also, the layer palette sucked, still sucks, and will probably continue to suck.

Pidgin? Libpurple is tremendous. If you want to see what Pidgin should look like, check out its sibling Adium, the best IM client on OS X (which uses libpurple).

I've been using Easy Peasy (http://geteasypeasy.com I think) on my Asus EeePC 1000 netbook. It is a solid distro based on Ubuntu 8.04. They plan on releasing 2.0 after Ubuntu 9 comes out in April. How does this Ubuntu Mobile compare? Is it friendly towards flash drives and computers with WiFi-only Internet access?

This. Can you sign in to Yahoo! with an OpenID? Nope, but they'll happily provide you with a YahoO! OpenID to use elsewhere.
