Re: WTF is this article talking about?
The paragraph from the reg does seem a bit strange...
"The firm pioneered touch for the masses with the iPhone, kicking to the curb earlier puny efforts from Microsoft with its tablets. However, touch on the iPhone is not multi-touch – that is, capable of taking input from more than one source, or person. Pinching and resizing a screen using just your fingertips doesn’t count as multi-touch."
Who says multi-touch has to be more than one scource. Multi-touch is defined by pretty much everyone as more than one point of contact, as DougS said. You can redefine to whatever you want such as saying "normal websites are not true websites, only theregister.co.uk is a true website", doesn't make it real until everyone else agrees with you.
Also, of course, the iPhone didn't pioneer touch for the masses. You could say that the iPhone pioneered a version of multi-touch that was used by 'the masses'*
*depending on your description of masses
However, in regards to DougS I would see that being able to distinguish between two different sources (people) is the claim. If two people point their fingers at a large ipad and move them apart the ipad will interpret that as "pinch to zoom", the same on android. Whereas detecting two different people would interpret it as two sources sliding their finger around independently. I'm guessing multiplayer gaming on a large surface is where it would help, although it could be simulated in software if each player controlled their own specific piece or were only able to play in a defined area of the board.
