You're not paying attention. Surface has been doing well and can do true multi-tasking with actual split windows. They got that right. It's Apple that took too long to get split windows available for iOS when it should've been released earlier on.
And for the record, Surface is growing popular by working professionals, especially in digital and graphic arts field. Trust me. I KNOW what I'm talking bout. Wacom and Surface are two of the most popular methods of input for the creative professionals, not iOS.
And it appears to me that the multi-tasking sidebar is actually a revamped version of the old double-click home button method.
So golden lesson for you is arrogance will bite you in the a$$ and it will Apple. Where's your beloved revamped Apple TV? Not here. Where's Apple's foray into Augmented Reality? Not here yet and falling behind. How's your iTunes and Apple Music? Oh wait, what a mess isn't it? How did you like Cue's messy live performance with his lazy getup? Open. your. EYES. Apple. is. getting. LAZY.
The Surface that's doing well is essentially just a touchscreen laptop, even the newer versions of the non-RT Surface are just touchscreen laptops. No, I will not trust you because it's obvious you have an extreme bias.
His arrogance? Have you looked in a mirror lately? Apple has NEVER forayed into that many technologies at once, it's not their MO to simply throw everything at the wall and see what sticks. Your use of words like "beloved" show such extreme condescension that I'm pretty sure you are oblivious to what's really happening with the products you are referring to. This is how you sound: "HAHAHA, you arrogant idiots!!! How's Zune, I mean Xbox Music, I mean Windows Music, I mean subscription/no subscription doing?!!!?!?!?!" That's how you come off.
