The only thing that really annoys me is that for bigger papers I always find myself running Word 2010 in a VM because Office for Mac is just crap, bad performance, bad features, bad gui.Do people that use Macs feel confined in any way?
If you need more than what an Open Office can give you or Apple's iWorks you can forget about a native Mircosoft Office that doesn't suck.
That is the only thing that really annoys me, because MS should be able to to some touchpad integration, get some decent performance. And put the damn 2010/2007 GUI 1:1 on top instead of this nonsense in Mac Editions.
And you are still stuck with rebooting to Windows for a game. I used to a little in between gaming on Windows sometimes. Don't ever do that anymore. Just too much hassle. Every few months I launch Windows for some gaming on a weekend when I am bored and nothing else is happening.
