Yes Darwin, but there is one major problem..
Some people perfer certain software.. Most of the time this certain software is required to run on windows, and WINE isn't good enough to make it work.
If I could run Steam, Jeskola Buzz, and Photoshop in linux, I wouldn't even have windows installed.. This is where the problem lies..
Not to mention the things you mentioned and many other linux users have mentioned to make it easier.
For instance, Unisys will probably have autoplay for CD/DVD's. Something that I miss in linux. I know it is easy to mount a drive, but the fact is that it can be a pain. I also look at this to be a gateway OS.. For instance, There may in the future be two different versions.. The version for the windows user to convert.. And the version for the linux user who just needs more system/software support.
