The only one of those requirements that it does not cover is the "decent battery life".

Oh, I see. I suppose I should have stated that it should have an internal battery. I want a laptop solely to use when not at a desk. I want to be able to haul it around easily. That's my real concern, and having an external battery doesn't help.

I should also have mentioned it should have the capability of 802.11b (specifically, since that's what I've got right now and I have no plans to upgrade soon).
