Started making the switch at our shop over Christmas (still at same shop as post #4 in this thread), but we at the sports desk have held out as long as we can. Everyone else is using InDesign, but I think we're going to wait until the break between winter and spring sports to finally make the switch. We wanted to at least get through this month, when we have to publish two 20-page basketball tabs a week apart.
Just remember that after coding one key you must repeat the sequence on all other keys you have for the car immediately after each other so they all get synced to the EWS module.
These days, I'm opening up InDesign roughly four times annually to do our department newsletter. Takes me about a half-hour to become comfortable with it again.
