So I tried the Trezor with the Electrum 2.0 wallet today and it worked like a charm. ...
curb your enthusiasm : ) there are a few issues if you play with electrum long enough. p.ex. it hangs when creating new wallet (like one with password, one without password), wait at least the bugfix release 2.0.1 is out. but yes, it looks very good and they did great job.
I've been using electrum development version from git for about half a year now with trezor. I only once ran into a serious issue and that has been fixed a long time ago.
