Soooooo what did Apple invent in smartphones...
Not the touchscreen, that was Samsung, LG, etc
Not 3G, that had been around for ages before it finally made it into the 3GS
Not phone cameras, Nokia had those for yonks
Not recording videos on your phone cameras, Nokia again
Not Siri (came from Nuance)
So, yeah if everyone stops being sued and gets back to inventing stuff they'll have something new they can put into the iphone5. Invented by people they stopped suing who could finally get back to working on cool shit (tm).
Oh hang they reckon they did invent something... Slide to unlock. (Though I still reckon the bolt on my garden gate, etc....) and possibly litigation as a method of screwing over your competitors when their shit starts to be perceived as better/cooler/slicker than yours (till you realise you need them to do all that inventing for you and you should 'settle').
Oh and that awful bloody connector iThings use so you have to pay 25 quid for a cable if you lose it.
Yeah. Inflammatory, also, but hey that's what the troll icon's for...
