um, yes OS X is the answer...
all that cool stuff windows just came out with for Vista, Mac has been doing for quite a while... oh, and while 2 Gb comes standard, I have 4Gb of RAM. The reason being is I run a TON of graphics, photo and video apps off of it (usually simultaneously for workflow reasons) and guess what... no problems. Vista just can't keep up.
Besides, what good is an OS that chews up half your RAM just by itself, and THEN has compatibility issues on top of that? Oh, and I have Office for Mac and it works very nicely
