By the way, that same hardware design was already present in a 1969 film called 2001 A Space Odyssey...
The icon-grid can be tracked back to Xerox' work (which was stolen by both Apple and Microsoft... Which is why Apple got denied when he tried to block Windows). We can find it on Palm Pilot devices (I already had an icon grid for the application launcher on my old Palm IIIxe monochrome)
Capacitive sensors were already used more than 20 years ago (I remind seing some of them on some microwave) and you can find some tools "out of the box" from microchip to make capacitive control panels (including sliders, buttons, switches and x-y zones)... Oh... and I should check but I think that it's the same technology which is used on touchpads on PC and Mac for years.
Tablet computers were already done by Microsoft (which was a big failure... well, Windows is not really made for tablets)
Gestures ? Well, ask to a 8year old boy who never saw an iPhone/Android, tablet,... what gestures he may do with one finger, with two fingers and you'll probably get the same list that Apple is trying to protect... It's trivial and as such can't (oops.. shouldn't) be patented.
On the other hand, Apple refused to pay for the 3G/GSM/... licences, saying that these should be covered because they are buying chips made by other who should have paid these... They have a lot of litigation about these technical patents (that can only be understood by people who are electronics engineers with telecom specialisation).
So, well, I'd like to see iPhone 4S Banned from Whole Europe and Korea... It could teach to Apple one basic law : "A bad peace is always better than a good war".
