Three of those million downloads was me. I got:
1) Angry Birds
The app store is a huge, huge improvement. It's such a simple idea I wonder why they didn't do it before? I find searching for apps for Mac (and Windows) to be a major pain. You never know who the developers are and if you might end up with a virus.
Especially with Windows downloading software is a nightmare. Many apps install themselves all over the operating system without asking. They make themselves default apps for files, let themselves start up on boot, force you to register and then start sending spam etc. Some of them are no better than viruses, even the supposedly legitimate one.
I only use download.com to get my Windows programs, but even then it is hit or miss.
The Mac app store should expand massively from the 1,000 they have now. Even I'm getting ideas for writing something. Let's see when they hit 10,000.
I couldn't agree more.
Although I don't use M$ products, and generally don't download that much software on my Mac, I can see how the App store would benefit me, and many others, especially those less comfortable with computers and others who don't trust 3rd parties (as you mentioned here).
