Nah, not really....eg the RM Tablet PC is actually a Tatung, PC Monitors are just rebranded with the RM logo, etc etc....however, they do assemble there own PC's (not fantastically well in my opinion).
I have personally found that RM are great at selling to non-IT-literate teaching staff.....its the poor techie people who end up suffering as a result of mis-informed procurement.
RM's tech support is truely shocking and a lot of there 1st line support people are unprofessional, lazy, unhelpful and even rude! We had a "common fault" issue with one of RM's slimline PC cases....they refused to admit liability for the constantly failing power switch, claiming that it was "user mis-use" causing the facia to break away. They finally admitted it was a common fault months later after being threatened with legal action.
I dare say there are some positive's with regard to buying from RM, but I have yet to see any!
