The point of using the Karoo as a phone is so you don't need to carry your regular phone (obviously).
Dealing with two phones is a PITA and expensive. Which is a strong reason one isn't likely going to see cycling computers do phone stuff (which is what I keep saying). There might be a few people who would want it but not enough to make the more-expensive device (which I also keep saying).
I think most people are thinking of using the phone feature for emergencies (that is, rarely).
The contact-syncing thing shouldn't be that hard to solve.
