Apple’s soon to unleash its Mac App Store. Similarly to the App Store for iOS devices, it will provide a central location for Mac apps to be bought, and Apple will take a 30 percent cut. In return, Apple will deal with hosting and billing, along with potentially providing visibility for apps from a range of developers.

Lots of people have said this is the Worst Idea Ever, presumably not fully understanding that most computer users never buy an application, and many of those who do get hugely confused during the install process (often running applications from disk images that they never unmount). A one-click purchase followed by a single-click ‘update everything’ button has the potential to revolutionise software purchase and installation.

The problem I have with Apple’s plans is that the existing App Store is horrible. Ignoring for a moment its terrible search and sluggish performance, the service is a bug-ridden mess. Every single time I try to redeem a promotional code, I am greeted with six error dialog boxes. Every time I try to update my apps, I’m told the information being displayed is ‘outdated’ and that I should refresh the page. Often, I’ll find that I’m being presented with an update to an app that’s no longer available, meaning the ‘update all’ button doesn’t work. Connection errors are commonplace. If this was just me, fair enough, but Apple’s support forums are littered with people suffering from the exact same problem—and when one error is fixed in an iTunes update or ‘behind the scenes’, another appears.

For me, this is a head-banging-on-desk kind of frustration, but for the typical iOS device owner it utterly destroys the user experience. If the Mac App Store suffers from similar errors, it won’t be enough of a step-up from the existing software purchase and installation model. For most companies, that would be fine, but for Apple this shouldn’t be good enough.
