My friend has one & I got to play on it a bit yesterday. Her's is one of the new Dell mini notebooks. She's using it mostly for school & email. The main drawback is that there is no cd/dvd drive, so in order for her to load MS Word & Excel on, she had to use an external drive that plugs into a USB port. It even came with a teeeeeny little mouse LOL - really, it was only about 2.5 fingers wide!!
It sure seemed to be plenty speedy & she said it has lots of memory. If I had the extra $$$, I would probably get one myself.
