A short snippet - the Windows XP version of the RM Asus minibook (also known as the Asus eeePC) was announced at BETT 2008, with availability scheduled for April.
Well the RM website is now accepting orders for them. It comes with a decent specification - 8GB of storage and 1GB of RAM - meaning that there'll be enough space for students work. People considering the original version (4GB of storage and 512MB of RAM) see that as a "browser only" device for students, whereas with Windows etc, it becomes a full-blown (albeit mini-size) student laptop.
More details and specifications on the RM website.
