I'm a long time roadie and somewhat techno abhorrent but regardless, I'm thinking of taking the plunge and getting a Powertap as a motivational riding aid. What opinions do you have as far as user-friendliness and reliability. I'm not a complete techno newb but I am rather resistant to learn foreign programs - is there a big learning curb with this thing? Sorry if this has been addressed before but I never can seem to make the BF search function work for me. Thanks.
