Funnily enough, in the UK, RM has released a rugged classroom laptop dubbed "RM Mobile One". RM is an education-oriented PC maker, so they know this market well. The Mobile One starts at £549, and is available now, sporting up to 1GB of 200MHz or 266MHz DDR SDRAM, 40, 60 or 80GB hard drive, and a choice of CD-ROM or DVD-ROM/CD-RW. The design of the laptop is based around children being not too careful with it.
The power port is designed to allow the connector to be pulled smoothly without damaging the connector or the computer should some errant pupil yank it out, RM said.
And there's an optional waterproof cover for the keyboard, which can be colour-coded to help younger pupils. A Kensington lock is provided for physical security, and the removable optical drive can be locked down too, RM said.
