I own 3 Kindle Devices, one Kindle App and have one more Kindle device on the way. Without registration at the Amazon site, syncing would be impossible.

Only if a person owns a single Kindle device would it make sense to deregister the unit and buy eBooks elsewhere.

For a time I used to compare eBook prices between Barnes & Noble, Sony and Amazon. Amazon had the lowest price for virtually EVERY eBook. Plus, Amazon offers thousands of eBooks free or at 99 cents or less.

I only read expensive theological, history and biography eBooks. The price differences on these types of eBooks are HUGE between various sites. Even with buying from Amazon, I keep a spreadsheet of all my wish list of purchase with prices and amounts of pages. I always buy the most pages for the buck. Even Amazon is still forced by some publishers to raise prices. If they raise them too much, I may never read those eBooks.

I tracked all those eBooks in a spreadsheet and eventually got rid of my Sony eReader and never purchased a Nook.

In fact there was a Federal lawsuit filed against 5 book publishers and Apple for collusion on maintaining HIGH eBook prices. Amazon was NOT one of the defendants.

Thus, it makes no sense to buy eBooks from anyone but Amazon but everyone has their own preferences. Most people I know do not buy eBooks. They still prefer the paper books at three times the price.
