Looks like those guys at Google have done it again and have released Google Desktop for Mac Now I look into this a little, haven’t actually installed it, but it looks like it comes up very short to the Windows counterpart Google Desktop for Windows.
At this stage Google Desktop for Mac looks more like a Quicklsilver replacement. I am a huge Quicklsilver fan but am also a big fan of Google and everything they do for Macs and Linux so I might find myself giving this a try. If I do give it a try I will let you know how it goes.
