Query: Avoid Sony at all cost!

Absolutely terrible product - bought a FZ 190e notebook in 2007. From day one the battery was problematic. Sent in for service and it came back with a note "works to spec for specified user mode" - translation the battery lasts 1.5 hours in normal mode. This is a brick that needs a AC adapter all the time. Also the mouse on the computer is horrible - have a Thinkpad from work and the mouse is 100x better. The only thing worse then the product is their customer service. My battery died at 14 months - guess what: the $400 warranty that I got stiffed for from Sony does not cover it. The single most defective part of their computer is not covered. BTW if you login into their site they dont have any history of purchases. So in summation: product sucks, sony website sucks, warranty sucks - I think that pretty much covers all the bases they could possibly mess up.
