If I had 3000$ lying around I didn't need for anything it's a safe bet that I would send them to Dynamism to purchase a Sony Vaio U101 - The World's Smallest Full-Featured Notebook.
This is a machine no bigger than a standard paperback that quite simply does everything. Full windows install. Swiwel screen so you can hold the machine in book fashion for reading. Excellent resolution. Size like a std paberback. Weight approx 1.2 kg with 8.5 hours extended battery life (or 800g weight with 3.5 hour life). To complete the picture, it has built in WiFi and ships with a 30 gb disk so it doubles as a creditable mp3 player.
What a brillian machine. One would consider travelling more just to show it off!

The weight and dimensions means that you really can keep it with you at all times (- you may need decently sized pockets but it's not like you're carrying luggage...) and the 8.5 hour battery life makes it worthwhile for simple tasks like writing notes, browsing and other light paperwork.

Product style bonus: It comes with a US layout keyboard, only with japanese sign subscripts on all keys and weird layout of the non-alphabetic keys.
