My 3G Kindle was delivered on Tuesday…I originally bought the wifi only one, but um’d and ah’d and upgraded my order. I managed to convince myself that free global 3G couldn’t be argued with.
I thought that with the wifi only version I would just make sure I have my next book lined up, but decided that I’d like the flexibility of being able to get the next book whereever and whenever. In fact I finished a book this morning on the train, and immediately downloaded another one.
My only gripe is the 3G coverage seems to be rubbish compared to O2 on my iPhone, but it still downloads books relatively quickly.
