I love my Edge and have had very few "anomolies" other than a few artificially high heart rates. The elevation data has been fairly accurate so far and I run my data thru the garmin software as well as Motionbased. Motionbased has never been down when I've been online yet although I have not yet upgraded to a full account yet. I may once dh starts using his garmin as well.

I DID set my garmin up with my bike data and it was fairly easy to input the weight of the bike and the wheel size from their chart. It is possible to set it up for 3 different bikes so next time I use my MTbike, I'll add that as well. I also use my garmin for running - I just carry it in my hand or pocket. It was awesome to have it on our bike tour in France this summer - so cool to be able to see the graphs and maps online.

FWIW, DH and I bought two Garmins for ourselves as a wedding present last March...

Enjoy yours!
