You can get an ATI FireGL in laptops now. The last one I saw was a T2, there might be newer ones out now. If you are doing rendering stuff like that you might as well get a rendering card
I know the IBM Thinkpad T42 can have a FireGL in it. I seem to remember seeing one in a HP not to long ago but I can't seem to remember the model number or find it on their site.
Well, at least that should make the decision a little easier. You wouldn't have many choices if you went with a rendering card, lol. Just be prepared for IBM to reem out your wallet. Believe me it is worth every penny though. IBM knows how to make a laptop. Hopefully Lenovo continues that tradition.
