(I'll buy a laptop to solve this problem, if necessary, but there ought to be a battery-operated device that will do these transfers with a lower power requirement.) The best solution would be for Amazon to create and sell its own brand of expanded storage media for the Kindle Paperwhite. I'd buy one. I don't want to jailbreak my Kindle, but I will if I have to, in order to get the ability to increase the storage with SD cards.
The cheapest that comes to mind is a netbook. Around $200-$300.
4000 is alot of books I don't think you get them all on your PW which only has 1.2GB of storage. You do get 5GB of Cloud though you can store books on.
