OS X on the EeePC - works. The linked snap shows my EeeBook with NetNewswire in the foreground, notes and a shell (where software is currently being installed with MacPorts) in the background. EeePC: 350 Euro. RunCore 64 GB SSD (fast!!): 199 US$. 2GB memory upgrade: 25 US$ (and I'll also replace the WiFi card so I can use the native drivers, so another 30 Euro). Finally Windows-free: priceless.
