Of some interest is Jack Dongarra's measurements on the iPad
And his speculation on a cluster. (wouldn't be a Beowulf: not commodity hardware, not open source OS, etc.)
While it might do the flops, the interconnect bandwidth is quite low. I assume it would have to use WiFi (I don't know how fast the tether port is, but I don't think it's a real ball o'fire. It's hard to measure. You can plug a USB disk drive into the photo adapter so maybe your interconnect could simulate that.

A rather nice Register article on costs for supercomputers, adjusted to 2010 dollars,
And a rather interesting cost per megaflop table on the second page.
