I think it's £29, which given the sheer amount of work Hans has done, is a very fair price.
What I don't understand is why people are saying the drivers should be part of the OS, as though they are in other OS!? Microsoft do not write graphics card drivers - of course not, the manufacturers do. Are drivers free on the PC? Again, of course not - they're included in the price of the hardware so it's invisible. Yet somehow some people think Hyperion should write drivers for all the graphics card - yet they can't possibly do that at the same time as develop the OS, given the size of the company.
What an OS maker should do isn't write the driver, but they should provide the API, which is what Hyperion do. Writing the API allows the graphics card manufacturer - or in this case, A-Eon, because AMD aren't going to do it - to support the cards.
In this case, if you don't want the latest graphics support, you don't need these drivers, you can stick with the current ones. And new systems from A-Eon come with the new drivers included anyway. So it's not costing anyone anything unless they happen to want the latest card support.
The alternative is simple - no support for later graphics cards at all. I think I prefer this option somehow.
