Hi  You may be confused
those "solutions"you  just mentioned are for Mac users desiring to Run MS Windows

Not for Mac OSX users Considering merely upgrading to the newest version of .....Mac OSX( Lion).

Cheers

No, -you- are confused. Those 3 products are ways of running more than one operating system at a time on the same machine. Sure, most people use them to run windows, but you can also use them to run Linux or even a second copy of os-x... I've done it in fact. If it were me, if my new computer came with lion, I'd just use the work arounds mentioned in other threads... Right now, I'm sticking with snow leopard until stuff like poser is updated for lion.
