Well, the beauty is that it is an entire computer the size of a credit card that will run Linux for $35, you can then program in almost any language, including basic.
Linux handles all the heavy lifting: file i/o, Ethernet i/o, real time interrupts, clocks and timers, etc, so you can focus on the programming.
There is a cable to bring out hardware I/O, so you can read/control anything without a lot more HW.
A LOT of bang for the buck. You can do the same on an old PC, but since it seems to be getting a lot of support in schools, there are already lots of example code and how-tos, and will be a lot more.
