A computer however, will be constantly changing data. A file that's rewritten very often (maybe a log), it would wear out the flash very quickly.

That's always been a concern with flash memory technology, but since he only intends to use it for an hour a week, and because most of the activity should be taking place in RAM anyway (since there's not really much need to page data in and out, except to load it the first time it's needed—and even that is only a read), I doubt that he'll see any trouble, unless he's writing huge amounts of data in his log files. His usage pattern is (presumably) so different from that of a normal computer, that usual caveat shouldn't really apply. In any event, flash memory tends to have
at least a few hundred thousand rewrites per cell (on average), and some good-quality, modern cards are reputed to be capable of millions of rewrites.
