Add a stylus and windows 8 and I'll be impressed. I wish apple would focus on minimizing the size (bezel) and weight of the existing ipad. I would love to see ipad and io6 dominate a super light consumption niche rather than splitting the difference and trying to compete with surface, Perhaps there could be and an ipad pro with osx and active digitizing.
'Aye Cap'n, You canna change the laws of Physics.'
Can't have a hand held touch device with out a properly sized bezel.
Can't have 14 hours of use without the capacity to hold an adequately sized battery.
Well, not until we get dilithium crystal powered iPads, with anti-gravity assist.
Can't wait for that patent.
I don't think Apple is 'trying to compete with Surface' I would argue the opposite.
I look at these patents as 'high ground' defensive positions. At worst, they'll use them to generate royalties (doubtful), at best, it will be when you've exceeded what you can do with a tablet, and you need to start building niche interfaces for subclasses of consumers (elderly, professional, mobile, academic, youth), each with a cover that extends the interface in a way optimized for them (artists... having a touch pallette off the 'canvas', for example).
It's a stretch, as it adds complexity to the apps to respond (what type of cover is there?... how present my app?... what happens when it detaches?). Dumb covers are just at the OS level... covers like these need to be exposed to the applications... that's not a short term 'let's add this' and see where it goes ala Tablet PCs of the 90s.
This just goes into the 'patent everything' pile. Sad we require this of our corporations.
