E.g. VIA onboard graphics: How often does this occur? Isn't that only on non-server stuff?
What I mean that if you buy something in a shop and the thing was created for Windows, how likely will you be able to run something composited.
The too new GPU case, I haven't noticed. E.g. you can run the binary nvidia driver, etc. No idea about R600.
It seems a lot like accepting the terrible state of GPU drivers on Linux. In this case I think raising the bar/requirements is acceptable. Meaning: a driver is not acceptable, it has to offer at least some features.
In any case, I said it is interesting. But interesting as in: if something else fails, it'll still work. But what if the other thing doesn't fail? In those cases, I'd like to know what Enlightment brings to me as a desktop. The question was asked, but the answer doesn't really give much.
