As a developer I appreciate this, but as a consumer I’m kinda bummed.
My cheapskate self took a shot while running the Windows 8 Previews from Developer all the way through Release Preview and I took every chance I could get to download and install apps I was even remotely interested in when they showed up in the Store. Why would I do this? Well, my thought was that once Windows 8 went to GA (General Availability, that is, available for everybody), these apps would likely become paid apps. And if they did, since I already downloaded the “free” version during the preview time, I’d get it for free.
Fruit Ninja, for example, was free until shortly before last Friday. Since then, it’s gone to $4.99. I saw this update come through and though “no biggie”
Foiled!
Again, good for the developers (like me), bad for the cheapskates (like me). So if you are experiencing some failed updates to apps you installed before Windows 8 went live, chances are this is why.
