"We've patented the Hell out of this thing, and we intend to protect our intellectual property" -- to paraphrase Steve Jobs during his iPhone presentation.
2007: Ballmer laughed. "No physical keyboard!" he bellowed. Most people couldn't see the point in an iPhone; over-engineering a problem that doesn't exist, they said. "Apple to add a physical slidy-keyboard in the next iPhone", everybody hoped (yes, really, there was a huge amount of speculation about that).
RIM laughed, and kept their phones the way they had their phones. Phones running Android slowly took away keys and made them more touch-oriented -- but that took some time.
Then everybody suddenly claims Apple are patent trolls, because now companies argue 'there's no other way to do a phone'. 'There's no other way to do zooming', oh, 'Apple have patented a rectangle. Hurr durr hurr.'
I think you'd feel much differently about your intellectual property had you sunk millions into R&D, hardware, software, supply chain, agreements with carriers where your phone is your phone -- the lot. Apple put their balls on the line, and the rest reap the rewards.
And what happens? 6 years later, we're reading "live by the sword, die by the sword" comments. This is MacRumours FFS, it's meant to be a community of Apple enthusiasts, not a community of people scrambling to write their oh-so-witty comment first.
