More importantly, cryonics is useful for preserving information. (Specifically, the information stored by your brain.) Not all of the information that your body contains is critical, so just storing your spinal cord + brain is quite a bit better than nothing. (And cheaper.) Storing your arms, legs, and other extremities may not be necessary.
(This is one place where the practical reasoning around cryonics hits ugh fields...)
Small tissue cryonics has been more advanced than whole-body. This may not be the case anymore, but certainly was say four years ago. So storing your brain alone gave you an improved bet at good information retention over storing the whole-body. I believe that whole-body methods have improved somewhat in the past few years, but still have a ways to go. Part of the problem lies in efficient perfusion of cryoprotectants through the body.
If you place credence on the possibility of ems, then you might consider investing in neuro-preservation. In that case, you wouldn’t need revival, only good scanning and emulation tech.
Edit: Also, I highly recommend the Alcor site. The resources there span the gamut from high level to detailed and there’s good coverage of the small tissue and cryoprotectant problems among other topics. http://www.alcor.org/sciencefaq.htm
