I used to have the BBC version a couple of computers ago, ran great in emulation under Win 2k on ... hmmm, was probably the Athlon XP machine. I've got the NES version at the minute because I have an android gaming tablet, so I get portable Elite
And actually I really like the NES icon system (although things like ECM are harder to get to - requires a bit more planning).
Both David Braben and Ian C Bell have declared the NES version their favourite, so I don't think I'm being too unfaithful
Used to play a lot on the Archimedes at school, and those solid polygon models are really pretty, but given I mostly game in bed on a laptop nowadays the old school keyboard controls aren't as convenient. If I ever go back to having a gaming desktop I'll probably get myself a "proper" version, but for now a portable NES will just have to do!
