As you are probably interested in OSX hackint0sh installations as I am, you might have heard about new gen of those distros. iDeneb brings OSX to version 10.5.6 and supports point upgrades.
Still, speedstep isn’t supported very well, because the battery lasts for exactly 1h:30min when almost fully idle (some web pages open, wifi on, display on) versus 2h:40min which Windows 7 beta 7000 managed.
Another problem is that resolution loves to revert to some unstandard and broken one when you restart computer manually.
So to keep things short, even though this “distro” is still unsuitable for a msi wind, I do think that it would be completely okay for desktop use.
