Who believes what Apple says? Most things Apple says are completely bullshit.
From the Mac Pro trash can product page(norwegian): "Enough performance to realize all your biggest ideas"
"You will never want more speed"
And let's not forget why Apple is sticking to 3.5" screens. It is the perfect size, and that's why Apple won't make phones bigger. It's definetly not because Apple is lagging behind. Oh, wait...
Never belive Apple's marketing. It's misleading and often false.
