We did a trial on the very first release of the RM tablet - you can probably still find the case study on the net somewhere.

What the case study will not tell you, however, is that the machines took a very long time to set up because we only had one external CD drive to install all the software with. They also had no real cooling device other than a heat sych so the processor seemed to be throttled severely to prevent overheating.

I am sure they have improved since then (if they do still do them) but it was a bad enough experience to put me off for good (especially as I am not the worlds biggest RM fan in the first place).
