Version 5.20 is better optimized. They have been working on it for years and that shows in the performance. Version 6.1 is very recent, still with errors and, above all, slower. Everything is slower: moving through the folders in the Library, accessing menus, opening books, following links... It lacks fluidity. I am not interested in changing the version, but everything is debatable. The good thing about PocketBook is that you can install any version you want. If you like version 6.1, you install it. If you don't like it, you go back to version 5.20. The best thing is that everyone tries it out and chooses the one they like best. There is already a Beta version 6.1 for InkPad 3, so it won't take long to get out. Here we talk about it...
