Patents.
Lets bring it out into the open, the reason apple have such lead and strong position is that because, by law, no-one is allowed to research into anything they've done.
Unlocking the phone by moving your finger across the screen? Patent. Sorry, no unlocking like allowed by anyone else.
How the menu [or any object] bounces back after hitting the end. Patent. No special effects of anyone else.
Multitouch. Patent [still wondering how andriod phones got around this]
And the list goes on and on and on.
This is what the article should have focused on; patents. All apples ideas are good ones, but no-one is allowed to do the same. Sure, you have a right protect your ideas but it "kills innovation". I'm strongly against patents. Fair enough to protect 'ideas', but limit it to 2 years forcing you to continue innovating rather than just strangle holding the industry for something stupid like 50 years. And apple has alot of patents.
But, the same also applies to the competition. It's rumoured that HTC is going for plam - not for the assest, company, name - but mainly for the [very old] patents in hope to sue apple.
This is why apple is king. Really, what's changed on an iphone in the past 3 [or 4] years? Nothing at all - just upped the speced and added some extra functions. Innovation? Sure, like 5 years ago. Heck, look at the ipad. Absolutely no innovation there at all.
