Ok, I've thought about this question. If you're high up in Andes, or need to do some business in rural areas, how do you bring your office with you without plugging into a wall outlet? The Battery If you're out about in the country every day, you need a battery that will give you power for at least ten hours. Check out the Electrovaya Powerpad 160, a 160 W-hr battery slightly larger than a sheet of paper 3/8" thick. The Computer On the PC side, if you want a really big screened portable computer, then look no further than the Xentex FlipPad Voyager. Quad folding design gives you two 13.3" screens to combine to form a large 20" screen. On the Mac side, the obvious choice is the Gigahertz Superdrive Powerbook which is the ultimate portable computer. You can burn your DVDs here too. The Printer If you ever need to print off that contract to sign right that minute, then the HP Deskjet 450 is what you need. It doesn't skimp on quality (1200x1200 up to 4800x1200), on speed (up to 9 ppm black, 8 ppm color), or connectivity (USB, Ir, or bluetooth). It can print off of a battery which can last up to 350 prints per charge. The Scanner If you have a printer, why not bring along a scanner? The CanoScan LiDE 30 isn't a bad choice. It draws power from the USB port so you don't need an AC Adapter. Its also nice and thin as it is 1" thick. Just some thoughts...did I miss anything?
