From each according to his ability...
Great, so in 2013, Windows Phones will be able to do what other phones already can today. And of course, the competition will be standing still in the meantime. But Windows Phone will be worth the wait, we promise!
As for Windows Phone 7.5 being "a very good start," it's not a "start." Microsoft has been trying for years to be relevant in the mobile space. So they finally got some of it right on the seven-and-a halfth try? Good for them. (OK, I know that Windows Phone releases haven't been consecutively numbered since 1.0, but you get the idea.)
Microsoft is in catch-up mode, and I expect that they'll stay there, as this time they're not able to leverage their existing monopolies as they were able to do when they initially missed the boat with the Internet.
I believe it's a suggestion that the investment was made based more on an ideological basis (i.e. the desire to be seen as supporting "green jobs") than on a robust economic analysis. Not that this has anything to do with socialism...
Yeah, because nothing built in the good ol' USA would ever be compromised.
It is an impressive accomplishment, and you should be proud of that. It demonstrates initiative, patience, imagination and maybe a bit of ingenuity.
There are some responses here that amount to "BFD" and you would do well to ignore those. There are others that put the scope of such a project in context, comparing it to what an undergrad student might do in a CS or EE class (and without much more experience or education than you have). I believe these responses are intended not to diminish what you've achieved, but merely to point out that it isn't rocket science (if you'll pardon the use of an old expression).
So, while similar things have been done before, it's still a monumental undertaking, and the fact that you saw the project through to completion says a lot. Again, nice job. The world (or at least some of us geeks) will be interested to see what you come up with next...
That's pretty much what we did in a CS/EE class. Designed a CPU from scratch, put the microcode on a FPLA and used a bunch of supporting TTL chips. If I recall correctly, it was 16-bit, but it might have been 8. He has taken it a step further with video output, and that's impressive (at least to me).
