I love my netbook.
I use it as a GPS navigation unit in the car. I use it with astronomy software when I have the telescope out. I use it as a cookbook when I am in the kitchen.
It is possibly the most versatile computer I have ever owned.
Until you are drive out into the country and there is no internet. Then it becomes the most useless computer you've ever owned, since all the useful programs on it are web based.
Plus I don't like the idea that personal or business work is on some server somewhere in cyber space where it is vulnerable to being stolen.
