I was originally going to get a Dell Mini 9. But the lack of customability for them stopped me. I'd love something with an SSD though. However the size of the SSD in the Linux version is only about 8GB to the Windows version 16GB. Which annoys me. As there's only a £40 price difference. Considering a Windows license can cost up to £60 for a disc and p&p I don't think the Linux version is priced fairly enough against the Windows version, especially when you take into account the cost per GB between an SSD and an old style platter HDD.
That said, once they get dual core atoms, custom colours for enclosure (like their bigger counterparts) and the keyboard layout is reworked and the fact they're much cheaper than the 901 from Asus, I'll probably jump on one. I want a little machine for penatration testing. And it would be nicer than lugging around a 15" one.
There's a Mini 12 (yep, 12" screen) out there somewhere, I haven't found any pictures though. 1280x800 with 1.3 or 1.6 Atom, Vista Home (lol on a 1.6 let alone a 1.3 CPU) or Ubuntu, 60 or 80 GB HDDs (must be old style platter HDDs) and a GB of RAM, slated for late November release.
Actually, I was searching while I was writing this. It's a Jap release only to begin with. Yes, its the Japanese Dell site, it looks like gobbildygook but the stats are there at the bottom. The Atom Z520 is the 1.3Ghz and the Z530 is the 1.6Ghz. (Look out for the Z540 @ 1.9Ghz in future). No move to 802.11n in the wireless area though (which is silly as my eeebox is 802.11n capable).
