We're testing a small batch of Compaq Mini 110's. They seem pretty sturdy and fit in a handbag without too much fuss. The keyboard is better than most of the crap that comes with smaller machines.
The idea is to get them as cheaper and more portable machines for teacher and TA's to use in schools. Our usual Tosh Satellite Pro's and Dell's are too bloody heavy to carry around.
Reasonable processor and a 160gb hard drive. on
eBuyer they are less than £200 inc vat etc.
Although we have Office licences for around a 1000 users, we have installed Open Office as it is free and bloody good.
