There are a lot of options, but we went with an Acer netbook. The reason we choose the Acer was the solid state hard drive. While it "only" has a 16 gb hard drive, it has three USB ports which helps downloading to a thumb drive. We opted for the solid state because I thought it might be a little more durable than the conventional hard drives. It is compact and gets the job done. Not super fast, but I knew that when I bought it.
