Eee PC + Vista
Here's what you'll need to get things started:
- An Eee PC, completely unmodified (4GB version, 512MB RAM)
- A SD card (you'll need this, 2GB minimum, the bigger the better. I'm using 8GB, which are nice and cheap now)
- A Vista DVD
- A 1GB USB stick
We don't know how well a Vista powered Eee PC will run, but even removing the storage limitation, the CPU is still barely above the minimum specs for the OS.
