Installed Win 7 last night and am amazed by how simple and trouble free it was.
Installed onto my Acer 6920g laptop, install was smooth with no SATA driver issues. Driver installation was minimal as most of them worked fine out of the box, other than me updating the chipset, audio and graphics drivers.
Program installation so far has been fine, a few older ones being incompatible but with Vista compatability mode selected all seems fine
Very impressed so far
