RAM is expandable so I went for the earliest I could get a basic board. $15 + $7 ship to USA. With luck I'mm have it mid-Feb. The goal has been laughably passed in no time flat.
If you want a 1G RAM (basic has 512M) then mid-April is the earliest until that block is sold. If you want to spend, they have packages with goodies and the t-shirt goes for $16, more than the basic board.
This will be my Linux machine.
