Now available in Singapore and you can order online. The price S$1,199 is steeper than the same model in US at US$749. It looks like early adopters have to pay more unlike the time I bought Compaq Tablet TC1000 with an early bird discount.
If you can wait, according to the brochure, there will be other models available with Vista Home Basic, FreeDOS and SuSE Linux Enterprise Desktop 10. This should bring the price down. Also, I don't see XP which is available in US as a option since XP drivers are already released.
