As for the prices, people pirated Microsoft, which kept their prices pretty low (otherwise no one would buy it). With a monopole for hardware, Apple can dictate its prices (already very high) however it wants and people can either pay or go for the small non-integrated OSes.
That would be a nightmare.
Apple is sitting on $100B in cash. If it really wanted to it could do a lot of damage with that much cash (not even talking about equity or assets, just cash). But it doesn't, it selectively invests while the tech journalists write articles about what Apple should be doing with that money.
Same thing with the iPhone or iPad.
Ummm... what about Ubuntu on the MacBook Air or Pro?
Then there was the whole Apple/Samsung thing.
And the App Store policies. I've seen people come crying to HN time and time again because their app got pulled or they can't update it any more.
I don't consider them a nice company and I don't find their stuff nice or usable. So you can keep the rotten fruit away from me, thanks.
