Over at The Gadgeteer, there has been kind of a group review of the 10.2″ Intel Atom-powered HP Mini 1000. Models reviewed included the 60GB 4200RPM PATA Hard Drive, which is the 1.8″ drive (similar to iPod drives) with a 3-cell battery. They’ve included quite a few photos.
There is actually a full comparison to a Fujitsu T4020 Lifebook, which has an older Intel Pentium M CPU and provides a good baseline comparison.
There is also, for those who are a bit more adventurous, a comprehensive look at running Mac OS X on the HP Mini, turning it into a “Hackintosh” or “MacBook Mini” as they called it. The HP Mini 1000 is considered one of the harder netbooks to turn into a Hackintosh because of some of the hardware involved.
