Math writing recognition in Mathematica and Windows 7

Screenshots here.

Have been waiting for this a long time. Already have the tablet PC with Vista on which handwriting recognition works perfect. So all I need now is Windows 7. That's at least a valid and worthwile reason to upgrade to Windows 7.

PI is female.

A formula for PI is
PI / 4 = 1 - 1/3 + 1/5 - 1/7 +1/9 - 1/11 + ....

I played a bit with this formula and it took me approx. 4000 terms to get the first four decimals stable. Beautiful but not practical.

I would say that PI is female.
