Here's inverted number row:

!@#$% ^&*()
12345 67890

I have tried the inverted number row, for a few weeks around 2005, but in the end i abandoned it.

One problem is that the numbers are needed often too, especially a sequence of numbers like credit cards, ID numbers, dates “2010-08-30” or if you do a lot scientific programing with code such as x^2 - 1/5 * 1.6. But now you need to press Shift for the numbers.

And if you type Chinese with pinyin input method (most popularly used), you need to type one of the number 1 2 3 4 about every 6 keystrokes.
