I'm not sure whether it possible to get them in Nigeria, but devices like Nokia N810 or Google G1 Dev. Phone can be very useful. They can stand by for almost a week. At least for me, here, in Nepal, these devices are very good solutions for electrisity outages. There are only 8 hours per day with power in Kathmandu (4 at morning and 4 at evening), but of course, mobile towers works 24/7. Some cheap netbooks with a 6-cell battaries is also reasonable. They could be used as linux-based test servers (without running X11.)
