www.msftncsi.comIt's not a big deal for me, but apparently it's a dealbreaker for some Kindle refugees that they can't start reading a sideloaded book on their phone and pick up where they left off when they open their Kobo.
Maybe other Kobo variants do better however.
Synching can be an issue. I had a one of the early kindles, and it was fine until I hit a few hundred items. It would re-index and be completely unresponsive for 10minutes at a go. That could have been done cloud side. In the end I decided I needed to purge loads of documents/titles to get it useful again. But accidentally sat on it. So game over. Moved to a simple Nook and SDCard loads.
It's easier to hold with dedicated page turn buttons, good lighting, and fast screen response time. Also water resistant and good battery life.
So far I've been able to get all the books I've wanted, mostly from the Kobo store, but it can work with any open format.
1. I can't highlight text across pages.
2. There's also an issue in which I navigate to some highlight and the text gets shown in a dark grey against black background, making it nearly impossible to read.
3. Since I can't highlight text properly (thanks to issue 1), I can't simply extract my highlights from a book, so I have to manually type it on a laptop, which is a painful experience thanks to issue #2.
