It is funny that Anders used Linq as an example of a language feature he does not deem possible as a third-party extension, because Nemerle does it very successfully. Is Anders really so uninformed as to say "I don't think that anyone knows how to do that" or does he ignore Nemerle on purpose?
After watching the video, I still have no idea what this is. Is it a new OS, a new version of Windows CE, or a new shell? How does it support third-party applications, if at all? Can it make phone calls? Does it support 24-bit colour or multitasking?
