Upgraded my student edition at a reasonably attractive price. I had licence key trouble (again). Judging by the slowness of response to my email support request (they're normally commendably fast), I'm not the only one. But, one replacement key later, I'm in business.

The product now looks much nicer, with anti-aliased fonts and graphics, and the last vestiges of Mac OS Classic-ishness gone. Except the single-level undo. Can that be so hard to fix?

There are lots of nifty new features, some of which I can actually use, but I'm disappointed by one thing: in providing native Intel support, Wolfram has dropped explicit 64-bit PPC support: the fat binary for the kernel (which does the calculation work) is now ppc + i386; it used to be ppc + ppc64. Shame! Now my G5 is not using half its bits.
