I'm still not sure about the new taskbar, especially launching a second instance of an application. Having to shift-click is annoying and obscure. That said, I'm not sure if launching a second instance of an application is still such
I'm also wondering if QA on the gadgets platform is more than an afterthought this time around. Developing gadgets for Vista's sidebar, especially if you're dealing with transparency or embedded media player controls, is a disaster due to how buggy the system
is. Initial testing of my gadgets on the Windows 7 beta wasn't promising either: they all broke.
