Buy Now or Wait for Revision B?

parisse: XCAS is a wonderful and a complete package mathtool. All components are well integrated and work together smoothly.

This is definitely NOT the case in HP Prime. And that is the biggest problem of the HP Prime: No consistence! The HP Prime is a patchwork of HP38/HP39/HP39gii and XCAS

So, why don't you port the COMPLETE XCAS on HP Prime?

Thats the way you can get a great calculator and a weapon against TI and CASIO !!!
