The argument most folks that love WP7 blindly is that they started from scratch to build what we know now as WP7 - totally disregarding that there's Windows CE 6.x lurking in there somewhere - and that Harmattan had been lurking in one form or another since 2005.

That latter part, not true fully. Sure the kernel and parts of Harmattan have been around for a while, but the Harmattan UI is pretty dang new. A small group of dedicated engineers put that entire UI/UX together and did it without massive amounts of funding, did it without the support Symbian has enjoyed... did it because that underfunded group wanted to do something special and did it in under 2 years.

And it worked. Lazy? I'd never say that about the Harmattan group.

And pertaining the pieces of stuff laying around that's "old" in Harmattan; older exists in WP7 still. It's going to take WP8 to break that cycle... by going to the NT kernel.

Which is... older.

That (to me) smacks of laziness.

I'm off of my soapbox now.
