I am more familiar with iPhone-only apps as far as Apple specific ecosystem goes and the "simplicity" if usually off-putting, it's just polished lack of features beyond the basic scenario. I suspect Mac apps might be similar compared to Windows/Linux, but don't really remember.
On Mac, I mostly used cross-platform (or multi-platform) apps, and they are about as good as on the other platforms * the amount of focus on a given platform (e.g. Outlook is behind the Windows version, Spotify is the same, some other apps like Eclipse seem to run better).
