I found the Dell the most attractive package in early 2010 for the follwoing reasons:

1. comes with the new Atom 450 (should be a little more nergy efficient)

2. the 6-cell battery gives me more air time than the 3-cells batteries in so many other netbooks.

3. the keyboard is a pleasure to type on quickly.

4. the case is not only pretty but sturdy. No noticable flexing of any kind under pressure.
