I like my -609
I got my p25-609 after my Sager fried a motherboard, and the repair place could not find a replacement
So the people at Philips (the warranty company) got me the Toshiba.
It's big. But it's not so heavy as my Sager was. The screen is pretty nifty, but keep in mind that the 17" is mostly length, so that it almost looks a bit short when one is used to more square aspect ratios. Mine has one dead pixel, but it's not super-obvious (check out Toshiba's dead pixel policy; I guess most manufacturers don't replace for just a few dead pixels, and Toshiba is no exception. Anyway, I'm not upset about the pixel).
The things is SUPER quiet (much moreso than my Sager was) and runs super-cool. The Sager tended to get VERY hot underneath, and, in fact, partially melted its case. The Toshiba hasn't even gotten very warm yet, and it's on all the time, doing some pretty serious number-crunching.
I don't mind the keyboard at all, but I WOULD like a separate numberpad. The touchpad feels nice, as do the touchpad buttons.
All in all, I'm happy (but see the cons, below).
Pros: lighter than my old Sager, but not much;
much, MUCH cooler than the Sager -- runs cold!;
much, MUCH quieter than the sager, despite three fans;
screen is a nice one, but not super-high resolution;
pretty solid feel;
runs damned fast (but I don't do much graphic design or movie editing;
lots of ports;
finally, the thing has pretty nice speakers for a laptop -- people have been very impressed at the sound quality out of two dinky little guys. Good stereo effects.
Cons: the screen aspect takes some getting used to;
one dead pixel on mine;
the graphics card (GeForce Go5200 from Nvidia) isn't acclaimed (I don't have much graphics card experience; it runs fine for me playing a few games, but perhaps with more of a load it would stutter. Also, the card doesn't have good linux drivers, so be careful using anything but vesa mode under linux -- this should be fixed pretty soon;
big (of course).
