I use the 701, but i plan to upgrade. Using either envice or a combo of fbreader and pdf2txt tools it works great. Fbreader will even let you hold the thing sideways and rebind keys. Imo it's the best way to go. (plus the eee pc 1000he has 7+ hr battery life).

A very classic and effective rat trap is a bucket of water. Build a ramp leading up to the lip of the bucket. Then build a rotating platform that has a chunk of cheese glued to it. When the rat jumps on the platform it will flip over and trap him in the water (how long can you tread water?). The platform rights itself and is ready for the next rat. 100% cat safe. Farms use this all the time.
