To be honest, I kind of find the thought of reading the same book on multiple devices a bit... confusing? I can kinda see it if one was smaller and easier to take on the go, while the other was used at home. But three????

My Kobo has orange light. Great at night. But it is not waterproof. Not so great for the bath.

My Nook Glowlight Plus is waterproof, great for the bath. But no orange light for night reading.

The Kindle... I have no use for the Kindle. But I hear how much people love them. I was given a Paperwhite 3, so I just want to give the firmware a fair shake. It is not waterproof and does not have an orange light.

File-wise, is there any difference between epub and kepub? I just found out that renaming a .epub file into .kepub.epub is enough for my kobo to interpret it as kepub.

kepub is an epub with extra spans, basically.

I agree. I mostly read ePub because it looks better. KePub I use only if I may want to zoom in on images or have enough footnotes.

I've found the WebKit renderer used with KEPUB to be a bit faster and more stable than the EPUB renderer, which is based on ADE. When reading long novels, I've had worse performance (very long page turns between chapters) and a couple freezes when using EPUB. The ability to hold the page turn button and rapidly flip through pages is also very handy with KEPUB, so I convert all my EPUBs before loading them on my Libra 2.
I find RMSDK to be more stable. As for the speed, there is no noticeable difference. I have KePub set to render with Kerning, ligatures, and hyphenation. But the issue with the first line of the next page and sometimes odd letter spacing is why I read ePub.

I've not had RMSDK freeze. I did have some issues with Access (KePub renderer) in a previous firmware where if I plugged the Libra 2 into the USB while displaying a KePub eBook, sometime it would look and I'd have to hold the power button to get it to reboot. The solution that worked is to go to the home screen and then plug into the USB port of the computer.

... and the kepub reading app uses those extra spans to keep track of your progress and also for annotations/highlighting.

If you sync, yes. If you download the ACSM from the website, you'll get EPUB when you redeem the ACSM in ADE.

You can also use kepubify from the command line, which is what I do with all my EPUBs before I load them onto my Libra.

That functionality was intended for use when doing a quick and dirty check on how a book displayed as a kepub. In a "real" kepub, each sentence is wrapped in a span. This is assigned a unique id. The location system uses these ids. If you just change the extension, when you close and reopen a book, you will always be taken to the start of the chapter you were in and stored annotations will not be re-displayed in the book.

The KoboTouchExtended driver and kepubify will add those extra spans for you.

Do you (or does anybody reading this) know how important the kobo.js file is to the renderer for kepubs? I know the KTE driver can use a reference.kepub.epub file in Calibre's plugin directory to copy the kobo.js file contained therein into its own converted kepub files, but also that KTE doesn't ship with a copy of this file by default (which is why it asks you to provide your own reference.kepub.epub file). But I'm not super clear on what configuring this adds. According to this page, Kobo eReaders don't even support JavaScript anyway, which would seem to make the point rather moot.

Just my opinion, I've never added kobo.js to any of my kepubs. I've never missed it.

Umm... the RMSDK renderer used for epub does not support Javascript. You do remember that Kobo uses 2 renderers? The webkit based renderer used for kepubs can and does support a subset of JS. To quote the page you referenced: "Kobo’s eInk and Desktop platforms have limited support for JavaScript, and do not support interactive JavaScript elements." Though I will admit the main attachment I have to the kobo.js file is one of the comments:
Quote:
Move directly to a page. Remember that there are no real page numbers in a reflowed EPUB document. Use this only in the context of the current document.
which appeals to my sense of humour.

All that aside, the main use of the kobo.js file is in the applications such as the Desktop App for Windows and Mac and Kobo app for iOS and Android.

OTOH, when you look at that page please note the majority of the content in the readme.md has not been updated in quite a while. The change last year was simply a change to email address for rendering issues.

As for me, reading the same book on two different devices is a pretty recent phenomenon. While I have had multiple ereaders for many years, I used to read different books on them. But since getting the Sage and the Libra 2, I've found that in certain lighting conditions (daylight and the kitchen lighting) I prefer the Libra, while on my reading sofa in the evening and night I prefer the Sage. So I mostly read on the Sage (I'm a night owl), except in summer, when it's daylight most of the time. I also use the Libra in the kitchen while waiting for the potatoes to boil and so on.

Current book, I'm going to likely jump between kepub (Kobo), ePub (Nook) and KFX (Kindle) as I'm determined to read a book on the Kindle I was given. Wish me luck!
I don't normally show page numbers either — but my Glowlight 3, without the update, so I still have hyphenation and better selection of font sizes — doesn't allow me to remove page numbers. On the PocketBooks I just hit tap the middle of the page to see what page I'm on when I stop reading. I don't display page numbers on Kobos either but, when I quit reading I do the same as I do on the PocketBooks, take note of the page number.

As for Kindles... I hardly ever read anything on them anymore. The wide margins and poor typography bother me. My favorite readers are my PocketBooks and the Glowlight 3 (without the update).
