I've replaced a Voyage battery and it is quite a bit more fiddly than that Youtube video suggests. There's glue under the shiny back plate which is a bitch to remove and you need to be careful you don't snap off the thin plastic clips that hold it in place.

The battery is also very well stuck down. I'd use a credit card when you get to that stage.

As for the Voyage itself...agree with above comments. I actually prefer a small form factor reader. With the origami case I can actually slip it in my jean pocket. Portability = more reading which for me is the main point.

The screen is also sublime and I don't think Amazon have equalled or bettered it yet, even with the Oasis. Perversely, and despite a huge premium, the Oasis line lacks the micro etched glass the Voyage has, and is therefore prone to more reflections. Warm light is a gimmick in my opinion. I used it on my smartphone where it makes sense but Kindle's all use ambient side lighting so for me there is no 'bright' lights when reading at night. It's essentially down to the aesthetic...do you prefer a shade of blue or orange.

I also prefer the Voyage page turn haptics. I frequently swap my hands when reading and having to rotate the unit to hold it properly and use the page turn buttons, like the Oasis, is an annoying inconvenience. Not an issue with the Voyage as the haptics are mirrored on both sides.

For me the Voyage improves upon the next best e-reader Amazon ever released...the Kindle 3 graphite.
