Looks useful for data logging and general experimental work in low speed scenarios. I'm currently using a TI 83 silver edition and a TI CBL and some Vernier sensors for this sort of stuff and it's a bit sucky but was essentially skip dived. As a scope though, forget it. You need at least 1-2MHz BW for something usable for even audio applications. At least 20MHz is probably a good idea. I have a 20MHz analogue scope (LG) and it cost me £10 (~$15) which is less than the Pi.
