Anyone else reluctant to buy through the Mac App store because of the perceived lack of uptake? For example, I've been a longtime owner of a Transmit license...it's worked for years now. If I don't keep up with OS X releases, I can still download past binaries and use the key (within a limit...for example, Transmit 3 owners were required to upgrade to 4.x). But what if the developer decides that it's not worth maintaining the binary on Transmit? Do you get a license key for the App store purchase? From my perception, once you buy into the App store, you're bound to its limited upgrade routine. This has bitten me plenty of times on iOS, where the developer doesn't feel like keeping up with iOS upgrades, leaving you with broken apps with no ability to get them working again. I'm not talking about fly-by-night developers, but AAA developers like Capcom.
