I remember, some (ten?) years ago on this list, there was an article about
making a cluster of Compaq Ipaqs PDAs. Those particular models only had
serial port and IR, so the author(s) went infrared. The performance of
them was dog ugly, AFAIR, compared to what I could do with one iPaq with
Linux and Python program doing similar stuff (prime sieve).
I remember iPaqs were at that time touted as would be student's digital
assistants, were to be introduced into US schools etc etc. Strange, seems
like history repeats itself. Am I a digital prophet? Is Apple going to be
bought by HP?

Extremely cool idea. How about stacking them all against a huge mirror?
