I find it to be the best modern answer to this question. You can find a pretty thorough walk through of Spaces over at Apple Insider.Īlso, today I use Moom (as mentioned by other commenters below). It is still very limited as a window management system and generally less useful than any of the third party tools mentioned in this thread so far. Mac OS has added to it's Spaces feature including the ability to have fractional spaces (two apps side by side) which is really just a first party version of the third part solution mentioned above.
