When a 10" netbook is too small but a 15" laptop is too big. This is a cheaper and faster (albeit slightly larger) alternative to the forthcoming Samsung NC20.
1200x800 resolution 13.3" screen, T2390 processor (dual core), 2GB RAM (1GB free), 120GB, DVD writer, Webcam
The processor isn't the fastest, but its dual core and much faster than Atom and Via Nano (as far as I can see).
You need to fit the extra 1GB RAM yourself, but this is easy to do.
