I've always wanted to have a play with an OS4 machine but the prohibitively expensive nature of the hardware has always put me off.
From what I have seen, OS4 doesn't really meet the requirements to replace most of my main computing needs. It looks like it might be suitable for light use, you know like browsing and generally tinkering with things, but it's hard to justify that when I need to own a more mainstream computer for other needs anyway. Plus it wouldn't replace my classic systems because I will always want to use my classic hardware for games and other old software.
For this reason, the cheaper the better really and if it comes out in the target price range I will finally be able to strongly consider it.
