Feneris,
Here are the specs I gave in another thread that are what you would want to look for in a Notebook:
If you want long battery life:
Intel Centrino
If you want great performance:
AMD Athlon64
Screen Size:
15.4" wide screen
Optical Drive:
DVD+/-RW

This is the Notebook I gave my wife and she loves it:

I call it my MAC Crusher.

Richard
