Personally, I really found the new combinations much better when Microsoft introduced them. I never managed to learn Shit+Delete, most of the time I wanted to copy (Ctrl+Insert), not cut, and Ctrl+C followed by Ctrl+V was so much easier than Ctrl+Insert followed by Shift+Insert.
Specially nice was that Cut (X), Copy (C) and Paste (V) are all together in the QWERTY keyboard, and all are enabled by the Ctrl key. By contrast, Shift+Del, Ctrl+Insert, Shit+Insert are simply more cumbersome.
And I think the exact think could be said about that Emacs and Vi key bindings too. They may be useful for the small part of the World that is the Emacs (and Vi) heavy user community, but bring nothing to the vast majority of us.
