This morning I installed eeeXubuntu on the solid state disk of the little Eee. It's pretty cool. The default Xandros in advanced mode was okay, but it was also a bit limiting.
So I tried out eeeXubuntu on a flash disk. Everything seemed to work fairly well, and I decided to install / and /usr/local to the SSD and /home to the 8 gb SDHC card I picked up at newegg for a sweet $30. eeeUser.com has a nice wiki about how to set it all up to maximize SSD life and minimize writes.
There's a few little hiccups.
