Not really.  The big problems that are driving developers away are policy problems (mandatory sandboxing that&#x27;s inadequate for the kinds of apps people want to write on OSX, lack of upgrade pricing, long delays in app&#x2F;update approval, etc.), but, as a user, I&#x27;ve been seeing issues with the app itself for a long time.  Things are particularly shaky around app updates:  stuff like clicking an update button and nothing happens, or clicking an update button and nothing <i>appears</i> to happen but the update starts downloading anyways and a progress bar doesn&#x27;t show until several minutes into a download, or Xcode updates that take (quite literally) several <i>hours</i> to install (after downloading) if you&#x27;re not running on an SSD.<p>These are things that got ironed out years ago on iOS, but I&#x27;ve not seen major improvements to the Mac App Store app since it was released nearly five years ago.  If anything, it&#x27;s gotten worse with subsequent releases of OSX.
