There is a Loongson based Nettop that sells for 263 USD. I believe Loongson based netbooks are the only 64-bit netbooks in the world. Gdium Netbook is not coming with fanless cooling technology. Hush Technologies is I thing providing fanless cooling technology.

I will also go for the Macbook Pro. It pefectly meets the requirements as mentioned in the first post. As the viewing angles of the Macbook Pro screen. Horizontal viewing angles are very impressive, while vertical angles are as expected from a notebook screen.

I have personally tested the power specifications for Acer Aspire Revo R3600. They is not more than one or two point difference in the both of the values as mentioned in your post. Idle power consumption 22-20W and Peak power consumption 25-27W. So, you can trust the figures given by the Internet.
