Bugs in massive undertakings like a kernel are unavoidable. It's a bitter pill to get a big improvement.

Using the wrong UI framework for dialogs or having links going nowhere is easily avoidable, it just needs manpower.

Actually, it's not excusable to have issues in the kernel or UI.

I just brought up the kernel thing because I was pandering to someone inventing poor excuses for MS. I shouldn't have pandered.
