Personally, the 'specs' for the new functionality in the 900 would not make me wait. I WOULD wait if the 900 offered automatic wifi uploading of my completed rides. If a $100 phone can do this (via Strava) why not a $600 grmin? THE biggest pain with a garmin is the required connection by cable to a PC to upload your rides. I will stick with the trusty 705 until that feature comes out.
