When connected to a monitor/keyboard/mouse, I don't really notice a difference between that machine and my real laptop. Obviously compiling the Linux kernel is faster on a real dual-core processor, but using emacs and firefox is just fine on the Eeepc. Even without the keyboard and monitor, the Eee is quite nice to use. The screen is actually brighter than my Thinkpad, and it's certainly higher resolution.
Anyway, I find his use of the term "the Asus" interesting. Asus doesn't even brand the eeepcs as "Asus" anymore. The only part on the laptop that says "Asus" is the serial number label on the back; everywhere else it says "Eeepc".
The downsides were - the small SSD made it useless for storing photos. I find I use my laptop a lot for offloading photos from my camera when I'm traveling. The screen was too small. The keyboard was small but I eventually got used to it.
I got a new macbook and never used the EEE again. However, I do miss the portability, and the new versions of the EEE solve many of the problems I had with the machine. Slightly bigger screen, more storage, etc.
She now uses it with XP and has a much better experience (for her) - We have a 20Gb USB hard disk that she can stick to the lid with velcro patches. Her only problem is with having to mount the drive via truecrypt from suspend but she wanted encryption on the drive.
I suppose the guy is writing about Asus 901...which is a bit different device..only 1kg weight, but with smaller keyboard and smaller disk space. AFAIK, performance is similar to 1000H.
