Yep, the subject line just about sums up my feelings on the Mac App Store. I love Apple products, but I'm not exactly going to herald the arrival of the all-too-overhyped marketplace with a red carpet or anything. This idea has been done before, with Bodega, only part of the revenue from sales (a big part) will go to Apple instead of developers, in exchange for a larger audience.
So what is it?
The Mac App Store is simply a marketplace for you to discover, install, and purchase Mac applications. If you have an iDevice, you're already intimately familiar with how the process works.
