Ignoring all the other stuff, you can sideload stuff to the unit. However, you can't use the dictionary and for me, that would be a deal killer. For this reason alone, I wouldn't use any Kindle that wouldn't register. There are many Kindles around that are NOT blacklisted - save your money for one of those. You will thank yourself for it.

Sometimes the kindles weren't stolen but were salvage. A shipment went astray, insurance covered it, it was found, and some dealer bought it from insurance company. Still, I wouldn't bother with one because there are just too many features that are blocked unless you can register it once.
