Not really. I use my Mac for Adobe CS5, Final Cut, Cinema 4D, you know, high end production apps you maybe have never heard of.
Of course you may ask, and thanks for doing it in a civilized manner.
For one, yes I don't really believe there will be much worth for me in it. The productivity apps (except Apples own Final Cut of course, but I think one will still be able to buy it in a box) I mentioned will most certainly not appear in the AppStore, as Adobe or Maxon will not give 30% of their revenue to Apple. The people buying these things know what they want for their needs. And no regular consumer will spontaneously buy the Adobe Suite for 2000 bucks.
As for indie apps, it might be a better choice, but I don't like to fill my Mac with too much stuff I won't use anyway. I know what I need, like Cyberduck, and where to find it.
But all of this is not the reason I'm against it. The main reason is that, with Apple, you never know. If the AppStore is a huge success, which it most certainly will be, there may come the day where it will become the only real source for Mac programms, with Apple as the censor above them all. And imo this is a really bad thing, because who is Apple to know what everybody wants on ones own computer, bought with ones own money?
This completely closed platform thing works great for mobile phones, but not for much more complex computers.
Apart from that, Apple will collect the data from everyone who ones a Mac and uses the AppStore. Profiles of what people like, what they don't like, what they download and what they use for how long. There will be buyers for that, be it other corporations or the government. And the way it works with deals between big corporations and governments, you won't even know about your data being sold to the highest bidder.
So, you can call me paranoid, which many of you will, but anybody can inform himself about some really bad things going on on the internet censorship/surveillance front. So if I see something that provides infrastructure for this, and I don't really see any actual benefit for me, it's an easy choice not to use it.
While I absolutely like my Mac Pro, my MacBook Pro and Mac OS 10.6., I don't have to like every single one of Apples offerings. I don't have an iTunes account either, as I'm oldfashioned and prefer to buy CDs.
I agree with your assessment, and I also do not trust Apple in this regard. They're the most proprietary player in the industry, and they put much effort into keeping their Walled Garden closed. This Mac AppStore thing in Snow Leopard is a test run. If it succeeds, they eventually -will- turn Mac OS X into another closed platform -- and, of course, they will claim that it is all about the customer experience, to make things easy for them.
I never liked the "it's our way or the highway" attitude behind the iOS AppStore, and I will certainly not support them when they bring the same attitude to the Mac AppStore.
But I also don't have any illusions. The Mac AppStore will become a massive success on the Mac platform. It would never work on Windows or Linux, but the traditional Mac customers are a different crowd of people, and most of the reasons why they will heavily support Apple's next Walled Garden will defy logic and... well, reason. It will be about something closer to faith into Apple's supposedly superior designs.
The Mac AppStore won't make it easier for you to download, install and update your software. It's already as simple as it gets with drag & drop and built-in auto-updates. So all that this AppStore does is make it easier for you to spend more money on an already expensive platform. But then again, this spending-money-thing is one aspect of the Mac experience...
