No problem running Poser or other 3D apps on a laptop. My setup is a Intel Core2Duo 2.4Ghz, 4Gb Ram (3.5Gb usable in Windows), ATI HD4330 256Mb, 300Gb Hard Drive. Came with Vista 32bit, but I replaced that with WinXP, runs much smoother. I've got a 15,6" widescreen, I used to have a regular 17", but I do not miss the size difference at all. The widescreen is wider, but less high, but I do not miss the height at all. I do find that the extra width is much more pleasant and usefull then extra height.

It handles everything well, Poser runs great, everything is fast and responsive. Rendering goes pretty fast. I also use Vue, Bryce and TrueSpace (to model), no problems there.

Just make sure you get one with a dedicated video card, it's a must, the integrated gfx are not that good. I also would recommend considering a quadcore, in the long run it will be worth spending the extra money for that.
