prusik | Oh, shiny, why do you taunt me so?

Mathematica comes in an almost affordable Home Edition, $295. Based on the Q&A, I gather that upgrade discounts will not be forthcoming and it is licensed strictly for personal use. I interpret "personal use" as "incredibly cool, expensive toy." Frankly, that's exactly what I'd use Mathematica for at home. (My place of employment has its own licenses for Mathematica Professional. My job doesn't really involve Mathematica though.)

Alas, it doesn't support Mac OS X (PPC), and it doesn't make much sense to get it for the increasingly finicky laptop. I will not be buying Mathematica Home Edition for now. Existing desktop still runs fine and really needs to hold me for another year or two. It's not like all OS X(PPC) software will instantly disappear off the face of the earth when Apple finally drops support for PPC.

If Wolfram allows two installs on two platforms on the same license (unlikely) and Mathematica ran decently on previously mentioned handheld computers (also unlikely), I'd be in heaven. Who doesn't want a fully functioning Mathematica in his pocket?

(I should point out that this is the same reason why I'd love to run Ableton Live decently on a handheld computer. Incredibly cool, expensive toy. At least both toys would share the same hardware. Live costs about as much as that hardware though, possibly more.)
