My LBS is getting a few of these in this Xmas and the concept is intriguing. I live in Canada where my trainer is used heavily for 4-5 months of the year, so I'm willing to invest in good system.

Currently on a KK Rock and Roll, Stages Power meter, using Trainer Road. Would the Kickr system have a major advantage over the setup I have now - or marginal (read redundant) - and not worth the investment?

Other considerations based on the little research I've done
- I don't own an iPhone or iPad - I'm all Android - so I can't take advantage of the App.
- I have a 1st gen Macbook Air (no BTLE) - but I do have the ANT+ stick that I use with Trainer Road. Will that stick provide the functionality that the Kickr offers (like ERG mode sync'd with a trainerroad workout??)
