I'm not for increasing your stock of gear mindlessly now, but here are a few things that have a pretty good purpose:
The Freeloader - For 60 dollars, you can get your one of these solar batteries. Runs you iPod, PSP, cellphone, or PDA for a good long time. Probably the best deal I've seen yet!
System 76 - sells Linux powered laptops, desktops, and server. Comes with technical support, the key ingredient that is missing from most other vendors.
Wind and Solar Powered Cellphone Network - Ok, so you're not going to go out and buy one of these. And you are probably not going to get to use it either, because it's being set up in Namibia. But see it get rolled out all over the world.
