If I can get one of my MSFT buddies to cough one up, hell yes, will dropbox the tutorial via pm. If they don't allow, that's that, but here is another article explaining it a little better, today's hardware can NOT use NT, plain and simple. And plopping a slow, terrible version can't be done either in the community due to other constraints as well.
Disclaimer: I work at Microsoft. But not on Windows Phone. Windows Phone 7 was built on top of Windows CE kernel (the same as Windows Mobile, and for those who are young enough to remember, Pocket PC and Windows CE Handhelds - this was in 1997). Windows Phone 8 is moving to NT kernel, the same one as your desktop operating system is using. NT kernel requires radically different hardware - specificaly, TLB mappings in pre-v7 ARM CPU contained logical addresses and this does not work very well on symmetric multiprocessor OS. So older ARM CPUs did not work with NT kernel, and move to the different OS kernel required radical redesign of the OS. Also, of course the desktop/server OS kernel requires significantly more RAM. With the large generational shifts it is not uncommon for OS to lose compatibility with old software. These shifts do not happen very often, but they do happen. For example, Windows NT did not support PCs with 286 CPUs (which were rather common when it shipped), or with less than 12MB RAM (something that is easily upgradeable on a PC, but much more difficult with the phone). Similarly, Windows NT 3.5 dropped support for 386 family entirely.
