I wish the author had included real life expectancy but that would take months and multiple redundant set-ups.

FWIW, I have had three of the cards in Pis running 24x7 with a sustained low workload of writes (logging and server log files), one for www.pidramble.com, and two for an internal data collection project, and have had no card issues in that time. The cards I've tested < 6 months include the 300x Transcend, the SanDisk Extreme, and the Kingston C10 (which may be slow, but is fine for basic logging purposes).

Thanks for the info :).

A good project for a student group though. Ten RPis, ten cards, some scripts to read and write and delete data.

In somewhat similar test, it took almost 11.5 million writes over 3 weeks to burn though 2401 EEPROM chip. [1]

SD card case is both simpler: no need for custom hardware, and at the same time harder: there is flash translation layer [2] between RPi and actual flash erase-blocks, so write patterns, block size, etc. do affect lifetime.
