I have what you want. Right here on my lap. Sony VGN-S150. Oops I guess there's been some model number creep.
VGN-S260
$1999
-Uses about 45 watts power peak, which makes it only warm when running.
-The vents in and out are on the perimeters, not the bottom. You don't have to worry about blocking them.
-The display is something like 114dpi, very sharp. Xbright is worth having. I've had mine out in the sun and it is usable.
-The hinge side has a nice curve to it for carrying (4.2lbs)
edit- The keybord is good. Not like the cramped version on Sony's smaller machines.
edit- BTW these machines have their restore software on a hard drive partition. It gives the option to make restore cd's.
There is a decontented
base model for $1446.19. You'd have to add back in some options, like the built in Wireless.
