When discussing Apple it is referring to just one device because they only make one phone - regardless of display size. But that wasn't my point. Every OS has had global issues with each release for what seems 2-3 years now. I'm not talking about OEM-specific issues, I'm talking Android, iOS and WM platform-wide.
Even if every OS has/had global issues I'm not sure "theirs" begin to compare to WP running 10, if I look back to 2010 then moving forward to today, I'm again hard pressed to write more than a few lines as to how any of my Android, iOS/Apple products, and PC w/past OS's, created such havoc and poor user experiences I'm seeing now.
OEM is furthest from my mind since to me it is pretty evident that 10 is the root of all evils here on both WM and PC. Having just obtained a 650 that was supposedly made for 10, I'm really surprised seeing how it mirrors the poor functionality I've experienced on my 830 (speed not part of the equation here), there have been lots of WTH! moments yet can't say the same for the other platforms... Either I'm one lucky Dude that only gets the best of the best w/Android and iOS and others, then picks the rejects on WM/PC, or, Microsoft's visioning of it's newest OS is way out in left field.
At the end of the day though, it'll come down to whether one's experience on each platform was good, mediocre or bad which will, make or break that user's perception for each specific platform. Right now and IMO, any general user venturing over to WM will find it broken with the overall experience being considerably worse compared to the other platforms.
