Yes, it's "windoze" if you like, but there are still older HTC devices that run WM6 better than the Tytn II does. Compared to the original Tytn (which is ROM upgradeable to the latest version of Windows Mobile), the Tytn II has more ram and a "better" processor, and yet it's noticeably more laggy in all kinds of apps, and offers poorer multimedia than its predeccessor, even when running exactly the same OS.
Just for once, this isn't Microsoft at fault here - it's HTC. They've cut corners somewhere, either on the hardware or the software, and produced a whole range of new devices that simply don't perform as well as their old gear. Now sure, they can tell everyone to just swallow that if they like, but it's not going to help their future sales. It also doesn't do much for Windows Mobile's unshiny reputation, and gives plenty ammunition to the Mikus's of this world, and I don't suppose MS are too enamoured of that.
Don't forget, these problems aren't just restricted to the Tytn II, they're common to a whole line of HTC products, including some that aren't even in general release yet.
