A netbook is a good second computer for taking on the road, but the small screen and keyboard would be a pain (literally) if it was your main machine.
I’ve got two in the house. I bought a 9” Asus and I couldn’t type! I spent half my time hitting the backspace button. I bought an Acer aspire 10.1” and it’s great.
I just watched Woot.com sell off a bunch of Aspire One’s just like mine for $224.95 shipped.
The advantage to these is that they are great for internet browsing, portability, and great battery life. Not a replacement for a “real” laptop or computer. I have different missions for each, and they are both great for their respective missions.
I don’t get headaches from reading these small screens and I need reading glasses to read written type. I don’t need them for the netbooks.

I tend to think that my choice to have a powerful laptop for the main computer is needless, since the netbook is the only one that goes anywhere.
