Perfect in all ways except one--speed – EZ-Digits HD Calculator Review

This is an awesome calculator. I've been using it well over a year and it's all one needs for basic calcs plus tape. But the tactile speed is terribly slow, given the processing power of any iPad. There's a brief but significant couple of milliseconds delay between every single key touch, enough to annoy those of us who are fairly fast keypad users. I can't believe the developers haven't improved on this yet. Here's hoping they do.
