I tried a couple of them out and I'm impressed with just how easy they are. I created an APEX app based on the PDF producing service -

Took less than 5 minutes from start to finish, one of the interesting uses (that I haven't put in that app but I did test) is that it could be used to produce a PDF of a chart or report region (by carefully crafting the URL) without the need to install FOP/BIP etc.
Things just got more Interesting ;)
