Let the hive mind of Engadget get that for you.
"What's the best gaming laptop for under 1,500 bucks? I had my eye on the P7805u (Gateway), but it seems Best Buy has run out for the time being. Also, as a secondary question, I like the specs on brands such as iBUYPOWER and CyberPower and the like, but are they reliable? I'm a little worried about buying labels that aren't huge like Dell, Gateway, etc. Thanks!"
My BT experience is *mostly* good. The negatives for BT are mixing mouse & audio simultaneously is difficult. If you do make sure your BT receiver is on a high-speed USB port and it's BT 2.1 or better.
Even then bluetooth drivers matter a lot. So far with Vista the Microsoft drivers have turned out best. Bluesoleil drivers used to be ok, but I've had bad stability with them after the latest versions.
