Yes, the technology for making a Wunder apparatus is certainly around; so is the technology for sending a space ship to the next star. However, in today's market place even so-called alliances give rise to modest technology transfer at most, and the kind of break-through device you envisage demand an extensive pooling of resources. That will only happen through take-overs, and even then with some built-in intertia.
Looking at Apple history, there is little precedence for technology sharing of that kind. Joint development, yes (to wit: AirPort, MPEG-4), but not pooling of already developed technologies. On top of that, the kind of mould-breaking device you are sketching out has not appeared in Steve Jobs' second term of office: the iComputers are all ideas based on what Apple was at first - the iMac was a Macintosh in Emperor's dress, the Cube was mainly an engineering concept based on proven technologies, the new iMac was a re-release of the Cube... it's a matter of in-house hardware innovation capabilities, and these are limited at Apple (in contrast to the engineering capabilities).
Ah, yes, the iPod! Actually it's again a matter of applying clever engineering to proven technology mastered inhouse, with an infusion of enlightened design added. The revolutionary parts here, apart from the idea of Apple jumping categories and opening a new frontier in an emerging market, are merging the newest evolution of a proven technology (tiny harddisks) and the OS necessary for the market segment. As is well-known, the OS is licensed from a small company (but would have been made inhouse if the window-of-opportunity had been slightly larger) - it is NOT the result of technology sharing.
As for messaging (SMS), that is just as huge in Europe, but it is tied to old technology from a mature market sector, that of mobile phones. Apple wants control of its new technologies, and that necessitates the in-house capabilities I keep harping on. Thus, Apple's next devices will be evolutionary, too - but the result of combining present capabilities in new ways.
