Interesting statement - probably sums up my frustration with Apple these days. I wish they were more focused on the quality of MY experience, not the quality of THEIR design.

Take a beautifully designed automobile and an ugly automobile and imagine that both are missing their engine. Would my disappointment towards the non-functional automobiles differ? You bet. I'm going to be exponentially more disappointed with the beautifully designed automobile not working because it's beauty implies purposeful design.

Likewise, a beautifully designed interface that's missing a core computing element (namely a native calculator app in this case), is going to elicit a disproportionately more negative reaction from the poor experience than an uglier interface such as the android platform- which incidentally has a native calculator app.
