If you own a Mac and you did your software update today, it’s likely you’ve had a bit of time to play with the new Mac App Store. I know I did, and the first (and only) thing I downloaded was Twitter for Mac, replacing Tweetie as my desktop Twitter client of choice. I won’t get into a written comparison (but here’s a side-by-side if you’re curious) since it’s not that big of a deal to me.

What did occur to me after browsing the App Store further was that I don’t really care that much about it. Obviously it’s a new and different way of acquiring desktop software, and I think it’s a good idea, but I’ve probably downloaded more apps for my iPhone(s) than I have for any computer, ever. I just don’t go out looking for new Mac applications very frequently once the need is filled, and new needs come along very rarely.

I’m willing to say that most of my needs are filled on my phone as well, but the two simply aren’t comparable environments. The need I’m generally still trying to fill when I browse the iOS App Store is that of a diversion – something that no one app can necessarily fulfill. When I’m at home on my Mac, I don’t need diversionary software because I have full-bore internet, a a big screen on which to view it, and unlimited bandwidth. On the phone, however, I’m probably more likely to be playing a game that works well on the small screen and with infrequent network usage, and the web is generally relegated to tool-status like many other apps.

None of this is to say that the Mac App Store isn’t a great success; I just don’t see myself as a frequent visitor. On the other hand, it’s already making for some great entertainment in and of itself.
