I ordered my Eeee on december 7th 2007 and was one of the happy, that got their machine still before end of january. It's a great, very usable device.
And here it is, the Eee900.
I like the comparison with the Psion5 and Netbook, as I was a very happy user of Psion machines since the Psion3 series. After all, it was Potters Scientific Instruments Or Nothing.
