The problem is that installs are all TL;DR. I'm quite happy that Windows finally has an app store, which gives them some control about what can be installed on people's computers while at the same time simplifying the install process. Of course, Microsoft can't force all windows applications to only be offered via the Store, but, it was adopted quickly by OSX app builders. I think people will be more inclined to spend a bit of money on apps too if they know they're safe and you don't have to dodge a dozen 'download' buttons or convoluted install processes that ask you to install crapware. But, that's just a theory; one problem is that there's a nontrivial amount of people that go to download.com on a regular basis to install c00l n3w appz. At one point, I did too - iirc back then the computer magazines would often point to download.com. Bet some still do.
