the dimmer would be no loss - the additional useability of the rotary knob to control the UI would be the thing I am interested in. OK, here's one customer already interested!

I still would be interested in a memory upgrade if it was priced up. Even at GBP 100 an hour, surely this would still be a couple of hundred if the memory costs were added? I am still interested - how far can the memory be taken out to?

I am far too attached to this box to consider selling it on (this comes as a result of giving her a name - see?) so even expensive upgrades are interesting; it's just new boxes appearing that cause the problem...

Seriously, if you were to look at any ideas for small hardware upgrades made available as factory-only retrofits, in a fixed-price menu of options, I am still sure you would have takers.
