This is interesting to me - I haven't yet purchased RM2 because I was concerned that my notes wouldn't sync properly or get indexed by Evernote, but it sounds like it's working for you? I've never emailed in a note to my EN account, but I regularly scan notes within the Android app and usually (sloppy handwriting aside) it can find my notes really well.
If this works by emailing in directly from the RM2 it could well be something for me to consider once more...
(Although I still think it's hugely shortsighted of RM2 to not think they should integrate better with third party apps.)
