I'm still having a helluva good time with my Sylvania netbook that I got back in November.
For the heck of it, I downloaded Puppy Linux and installed it on a USB stick. The netbook boots the Puppy from the USB and, viola! It's a cute-as-can-be system and runs fast as blazes. I changed the appearance around a little (the snowman wallpaper), installed Opera, then saved it all back to the USB stick for next time.
It was fun on a cold night.
