I have the 720 and PC interface (no power monitor options). It is a fairly interesting toy but has a
huge flaw as compared to my $30 cateye enduro - there is no way to see the current ride mileage! It
is only available once the data is downloaded. This to me is a serious oversight.
Not sure why you say the altimeter is not sampled? Mine is and plots on the PC.
The wheel sensor and HRM wireless interface have proven to be very reliable BTW.
I've places an example graph of one of my rides a couple days ago here:
