Notebooks are getting slimmer and lighter like the Mac Air. I just got my hands on an Ultra-mini notebook (UMPC) that weighs less than 1kg, and it is perfect for me when I travel and do presentations. And the price is incredible. A small mouse comes in real handy. My normal optical mouse does not work on a white surface! It gets kind of embarrassing to present to your client when your mouse does not work at all! I got myself a laser mouse and it works great for me. I wouldn't mind getting my hands on this world smallest laser mouse. Does anyone know where I can get one?
