An editor over at laptoplogic forums has written a very interesting piece on the feasibility and usefulness of laptops as gaming machines in general use. Typically we don't think of laptops as being gaming beasts, although the majority of geeks who travel will have a laptop and likely play games on them. The advantages of low power and increased desk space have convinced some people to switch to laptops completely. For them, often performance is a must.
The article covers things like battery life, performance and size. An interesting read, definitely. Check it out here.
