LaptopMag tested the preview version of Windows 7 Ultimate on their ASUS Eee PC 1000H netbook and report it runs pretty well:
This morning we loaded Windows 7 Ultimate (Pre-Beta) on an ASUS Eee PC 1000H. And just as Microsoft said: it works. The Eee PC running a 1.6 GHz Intel Atom processor and 1GB of RAM handles the new operating system pretty well, just as it ran Vista pretty well when we loaded Vista Basic on it a few months ago. We still had a problem getting a few of the Eee PC drivers to work with the system, but for the most part we were able to get all of the features to work using the XP drivers provided by ASUS.
Unsurprisingly, it takes 58 seconds for the system to boot the OS (see the video below). Of course, it has actually taken a minute for some systems to boot XP as well. However, the Eee PC 1000H boots in only 40 seconds with its default operating system.
Once booted, it was pretty neat to see Windows 7 on the 10-inch screen. As we mentioned in our Windows 7 overview, things pretty much look and feel like Windows Vista.
