What is sometimes frustrating is when I have made 3 or 4 highlights or annotations in a short period of time and then I have to wait for my Kindle to save the changes. Hopefully the OS on the newer Kindles has resolved the file wait problem between the index files, the book annotation file and the MyClippings.txt file.
Interesting, I've run into lags with the Touch, but not when saving. I'd hate to swap this one and be frustrated with what you're describing. Going to give it a couple more days and decide. Thanks for the info
