I have looked at Excel 2007, and the major thing I miss, is the ability to
changed / customize the menus, as it is possible in Excel XP (and 2003 i
think).

I am a keyboard user of Excel (working with the mouse is much slower, and
gives me pain in my arms/hands/shoulders and neck), so I have customized my
Excel with a lot of extra functionality in the menus, so that I don´t need
the mouse very often. And that is great! And very efficient!

In Excel 2007 the menu are gone. The ability to customize them is much
poorer.

Is MS only thinking of mouse users (and not of number cruchers like me).

If MS does not make the menus and customiziation available in Excel 2007, I
will stay at Excel 2003 !!!

By the way: The extra colums/rows in 2007 is great (I hope this also means
that it can handle much lager sheets - with more than 65.000 formulas...).
And also I can see that the functionality has also improved.
