When will these devices be compatible? Currently, I cannot download/transfer data to Garmin ANT+ stick from 910xt on my Surface laptop/tablet and it is really frustrating and inconvenient. To download workouts to Garmin Connect or TrainingPeaks from my 910, I need to use my girlfriend's MacBook which SUCKS!!!
Not likely. At least not from Garmin, and given how the open source community typically feels about Windows platforms I doubt you'll see any motion there either.
