Carlos...
Another quick thing about gigging with a "portable"...My Qosmio had the "typical" battery that really didn't last all that long with extended use away from AC. So I put in a huge heavy duty battery and that more than made up for the stresss I developed using just a standard size. It was damn near as big as some of the Netbooks, themselves. And the new netbook battery compartments look like they were made for Toys-R-Us products...so seemingly tiny and fragilely-built, that I fear they would break if knocked against something substantial.
Just another errant thought.
