Any reasonably eqipped laptop available today should suffice for SC4-RH. Most laptops are at least as good as most desktops. Good playing parameters for SC4 would include 2.0 GHz (or better) Pentium processor, 1GB RAM and a dedicated 64MB (or better) graphics chip. My system is a bit overkill for SC4 (but I run a few true 3D games, which SC4 is not). My system specs: 2.20MHz Pentium M, 2GB RAM, 256MB ATI X700 graphics chip.
