I agree, a usable app that allows the interface of the mobile app for the Mac computers would be nice.
Its my understanding that with the changes in the current Mac OS, writing the mobile app and the desktop app for mac is almost identical, you just have to allow the desktop Macs to “See” the App in the Mac App Store.
So since they already have a iPhone app, its only a minor change to port it to the Mac Desktop computers. From what I understand, it really is only a few minor changes.
So a Mac app that allows a live interface should be fairly easy since you already have 90% of it already written.
