Agreed.

No, I think the right fix (although I'm not on the Calculator team) is
to keep it evaluating as you type, but *if* the expression results in
a syntax error *don't* show that (instead, a blank or the last result)
*unless* another key has been pressed.
i.e.
Typed | Display
-----------------------------+-----------
4 | 4
4 + | 4
4 + 2 | 6
4 + 20 | 24
4 + 20 - | 24
4 + 20 - / | syntax error
4 + 20 - / bksp | 24
4 + 20 - / bksp 6 | 18
Hopefully that makes sense.
Cheers,
Andrew
