Is it a bad idea to just drag and drop a library with 2,403 books onto a new kindle? I know that my older Kindle Keyboard models always had a hard time with this with the indexing aspect. Is it easier and less intense on the hardware of the newer Kindles? I have yet to upgrade to a new model. I have been buying used Kindle Keyboards for a couple years now since I love that model so much but now that my three used devices are all giving me issues it's time to upgrade to the Oasis. I didn't know the best method to get my entire library on the device. Thoughts?
