> when so much focus is assigned to those instead of the core pieces of the OS
Do you have any evidence that Notepad and Task Manager required "so much focus"?
The new Notepad's about as bare-bones as the old Notepad, it just happens to use XAML Islands for the UI. It would be surprising if it significantly detracted from other efforts.
It's all about contrast to everything else. If my house roof is leaking and instead of fixing that I put a limited amount of resources I have into repainting my office and installing a fancy new European faucet, and then go and tell everyone about it - that says a lot about my priorities.
Yes, I am fully aware of the fact that different teams do different things at a big company, but funnily enough when asked about high-priority issues the answer is almost universally "We don't have enough time and/or developers to tackle this right now." But there is magically time for MSN toolbars and Notepad tweaks.
