Moved to Cinnamon section.
Backports for Maya explained here: http://blog.linuxmint.com/?p=2225
. Whether you want to use the newer Cinnamon or not is up to you. The current version 1.6.7 has some fixes and small additions as compared to Cinnamon 1.6, so you can review the introduction of Cinnamon 1.6 here for the major improvements you are making yourself miss out on: http://cinnamon.linuxmint.com/?p=207
. Nemo, the new file manager for Cinnamon, has seen more changes but here is it initial announcement to give you some feeling for that: http://cinnamon.linuxmint.com/?p=198
. Both are very much still under active development, with Linux Mint 15 promising even more awesomeness for both.
If you have a broadband Internet connection, you could download Linux Mint 14 Cinnamon, but that on a DVD or USB stick and try it out live to see if you like the new Cinnamon and Nemo.
