Really simply Andy... The point was made that the Windows Store app "taskbar" was akin to the W7 taskbar. I suggested it wasn't because, according to some, Windows Store apps aren't meant to be closed therefore the taskbar was more akin to an MRU list. EvilD asked me how I'd improve it and I gave my opinion.
Great apology... er... I mean thoughtful post.
Let's just call it a big phone shall we?
