its probably not impossible in future to run other os on it but the drivers are gonna be a problem.

I wouldnt say that.... You know the linux and netbsd folks will do what ever it takes to get their platform running on that hardware. linux ppc on mac is very well supported right now.
We will most likely see linux on the new macs first. I think it would be in microsofts best interest to support the intel mac on their new release of windows. I would buy a copy of windows and dual boot osx on an intel mac.
