Now that the MB has been updated, I'm considering replacing my trusty G4 1.5 Mini with a Blackbook. It would be used 95% of the time a desktop replacement with my Dell 2005FPW and Apple keyboard (iLife, MS Office, some ArchiCad). But it would sure come in handy as a laptop on those rare occasions when I need portability. I do have a few questions however about the MB as a desktop replacement: how does the reliability and longevity of the MP compare to a Mini? any overheating issues with the MP used constantly in clamshell mode? MS Office would run under Rosetta, so would there be any significant speed gain/Loss as compared to my G4 Mini? any issues wiht the mini DVI connection on the MB as compared to the regular DVI on the Mini? will I ruin the battery if it is only very occasionally used? Thanks in advance for your advice. Cheers.
