A moderately ironic moment - we wanted to watch the Republican VP candidate give her speech this evening, so we headed on over to the Republican National Convention website. Right on the front page is a nice 'watch live' link. Which apparently doesn't work on Macs. So we headed over to CNN. Same thing - video wouldn't play on our mac. There's a vaguely funny joke in there somewhere, something about being different and Republicans, but I'll leave it as an exercise for the reader.
I've had the same experience, though I'm not using a Mac. Ditto for the Democratic convention.
I'm assuming that I'm just not in their target demographic. ;)
