I thought this might be of interest here.
I did a work presentation using an Apple IIe. It actually
went surprisingly well and was well received.

(http://home.comcast.net/~mjmahon/AppleCrateII.html) and use a matrix of
16 projectors for double double double double hires and 2^4 more
nerdcred. You could also add 16 channels of sound. :-)

Given the increasing interest in the Green500 (and that the topic of
your PPT was Energy/Power profiling), the iPad was actually more energy
efficient.

True enough, though at 18W the IIe is better than the macbookpro I might have used otherwise that draws 32W, at least while running Linux.

If you watch the video you'll see a dev board on my desk hooked to the LED display. It's an ARM Cortex A9 pandaboard and we can get at least 1 GFLOP/s out of it while only drawing 5W. Probably more useful than a massive array of 6502s but not as much fun.

This makes me wonder: Is PowerTop inaccurate compared to a real physical measurement tool?

Granted, it gets into the 20s if I open something that hammers on the CPU/GPU. Not as pretty as a macbook, but I have more than enough money left over to wipe my tears of anguish with 100-dollar bills and still have spent less money than I would for a macbook.

The macbook pro is 32W with backlight on full, and wireless and wired ethernet enabled. X11 is not running though.

I am measuring this with a WattsUpPro power meter, so it also includes any AC/DC conversion inefficiencies. I'm not sure exactly sure how powertop measures power; I'm guessing through ACPI somehow? The macbook doesn't report power if I run powertop on it.
