Well, I strongly recommend an AMD notebook, preferably an Athlon 64 one. Yes I know poser does not support 64 bit yet, but A64 has improved architechture (on chip memory controller vs.) and runs like a dream. You have no luck with Intels if you are using cpu-intensive apps like Poser. They suck big time. When it comes to rendering, my 165$ A64 overclocked to 2.8Ghz (3000+ venice) is %75 faster than P4 Extreme which costs between $900-$1000... Hope that helps...
