It took me 4-6 hours of troubleshooting to get Electrum 2.0 working built from source on my Mac. I didn't try on Windows, but I imagine it is more difficult. If you're using Linux, it shouldn't be that bad, follow the "Development version" instructions here. You also have to have the python-trezor python module installed. Using it is as straightforward as Electrum with its own wallet, once you've satisfied the dependencies.
People not familiar with a shell, git, python, etc should probably wait for 2.0 release binaries. Especially if on windows (just a hunch, I might be wrong, cygwin might help).
