Ordered mine in June, got 'em yesterday (or was it day before yesterday?).
For $2.15 each I am certainly not complaining.
The folks at hackaday gave a short tutorial on how to use an open source toolchain under linux, which makes them more useful to me, but I suspect the most I would do with an MSP430 is make an arduino peripheral out of it.
first step, blink the LED. Second, make it talk I2C or SPI to the arduino.
