Here’s a useful device: the Monster Outlets to Go 300 turns one AC plug into three and provides two USB outlets. It would be cool if you could go USB-USB and charge a laptop without the proprietary power block and cord. That would save weight, but I assume that’s impossible (I checked - it is impossible). At least this adapter would let you charge your laptop and USB devices at the same time, without plugging those devices into the charging laptop. (HT: Scott Carmichael at Gadling)
