netbooks/mini laptops

I couldn't find anything on this using search. does anyone own one or have any recommendations for/against getting one? I travel quite a bit for work and this seems to be something I could use. the laptop I have now is a bit cumbersome to lug around, so I don't always carry it out of town with me. I use it in the evenings after work at the hotel to surf the web and listen to music. it's not at all for work or anything work related-just for my personal use. any advice or suggestions will help. Thanks.
