Anyone remember Inmos? The point about them that I am thinking of is they came out with some CPUs which were groundbreaking both in terms of design and of performance ... but eventually failed as a company. Their CPUs were overtaken. They tried to come up with a radically faster machine but had trouble with it. It might have been better it they had come up with a number of evolutionary revisions rather than going for something so much better in one go.
So, for their own sake should the Raspberry Pi Foundation have a programme of evolutionary model upgrades? Of course, that would raise compatibility issues but to an extent they have already released a small set of model variants and people cope. Or should they have a broader range of models? Maybe they are already working on further revisions. Anyone know?
I suppose I should ask if there is anything worth improving on the Pi? I suppose the CPU could be faster but that might require active cooling hence would not necessarily be a good idea. So ideas for improvements would need to be practical.
