Window managers assume the display area is a rectangle equal in size to the heighth and width of your total desktop. If you use more than one display resolution in a Xinerama setup your desktop will be non-rectangular. This results in "dead areas", areas which do not exist on your display, but window manager interpret as "Empty". Many window managers will try to utilize this dead area for new windows. The result is windows which are inaccessable. As window managers become Xinerama aware and this problem will go away quickly.
So it looks like this is the Window Managers fault, not Xinerama's.
A problem I see with this is that you may actually get people who buy RedHat 7.3, and are currently windows users. Ok, so what? That is the point after all.
But then, these windows users try to use Redhat, realize they don't know what they're doing, or that they can't do things they could in windows, and then get turned off of linux. Then they go around telling everyone and their brother about how Linux sucks, and the whole point of the rebate, which is to get people to switch from windows to Linux, backfires.
RedHat still isn't ready for everyone. Even though it's great for some people.
