Amazon ad for Mathcad

I was browsing Amazon for a Depth of Field calculator (photography) and up popped

www.ptc.com/go/buymathcad/ - Mathcad 14.0 with advanced features Solution to scientific computations

Wonder if that works on my PalmPilot, or if I must carry my laptop to calculate DoF in Mathcad? ;-)
