I am debating that question myself.
I usually have wi-fi available, but not always. And one of the main reasons I am considering moving to a new Kindle is that I haven't been able to make use of the sync capabilities as I don't have Sprint coverage at my home. I was actually considering a new reader even that before the new Kindle was announced, because I live in an area where I have better AT&T coverage than any other provider and currently have the US model. So is it worth the extra money? Or would I be risking missing out on the sync still if I don't get it?
Decisions, decisions...
