Laptop suggestion!?

[Corbin Wells]

Hey there! I really need some help on picknig a labtop. I need something that would go great with photoshop because it's primarily going to be a work labtop and all of my work will be photoshop based, hence animator. And I also want that same labtop to support Stepmania with no problems because I'm going to be using that much as well including having it be able to support a metal dance pad and an S-Video slot so that I can hook it up to the kick ass TV at my college and host stepmania tournaments! I really need an expert opinion on this and the labtop I should buy. Someone once suggested a Mac, and another says it doesn't matter but after all of the harsh criticism of VISTA I am dreaded to go near it...
