I like the latest firmware, myself, but you may not if the tiled home screen is important to you. You'll only see a max of 4 recently opened books. Finished books automatically disappear from the home screen.

The things I like most are the menu in the top left corner which now means you can go to anywhere from anywhere. I also like the extra Authors tab under My Books as it makes it very easy to see all books by a particular author without needing to do it via Collections.

I think most patches are still available but a couple are no longer possible. I can't remember off-hand which they were because they weren't ones I use. You'd have to read the various fw Patch threads by GeoffR to see which ones bit the dust.

If you upgrade and decide you don't like it, it's not the end of the world, as you always have the option to go back to whichever fw you want. It takes a bit of time but there are no technical barriers.
