I do have a mac... that's why I said "for all you PC users"
I don't force anyone to buy a mac though, and let's try not to turn this into a mac/pc topic either...
But for mac users, you can download Bodega: Your corner store for Mac apps
It doesn't offer an all-in-one installer but it's a massive collection of applications (both free and paying) with links, reviews etc. Sometimes you can install the app directly from Bodega, sometimes you'll have to click through to the download site.
