What ebook reading devices work well without Windows or Wine?

I want to purchase an eBook reader device and eBooks.

Purchasing an eBook (or eReader) is just like buying a computer. You first have to identify the software ('books') that you are going to want, and which 'platform(s)' supports them.

For eBook purchases: Amazon is the market leader (in terms of selection, market value, or market share). Barns and Noble (Nook), Sony, etc., are other alternatives ..

For free eBooks: The Internet has myriad sources for (quite literally) millions of titles. Most are in .epub and .pdf format, but plenty are available in the format of your choice.

I don't use Windows, Mac OS or Wine.

You don't need any of these. The suppliers want you on their website. For example, Amazon.com actively encourages you to send your purchases directly to your device. This can be done a any time, by 'syncing' your device. Anyone can do this, without any technical expertise ..

Most suppliers support (or allow) downloading the file to your PC. The device can simply be connected via USB, allowing easy management of all content.

Most eBooks sold today are encumbered with DRM.

YES, that is true. And these eBooks are NOT intended to be used on multiple platforms (eg. Nook and Kindle). Sadly, this is about protecting their market share and NOT the authorship ..

Therefore, I need a workflow to buy and read DRM eBooks either using only the device or using Ubuntu.

You ONLY need Calibre and a browser.

sudo apt-get install calibre

Calibre will manage your (ever-growing) collections of books, convert between nearly ALL possible formats, has a built-in eBook reader, and will connect and manage most devices.

It will NOT convert the format of DRM eBooks - but unless you have multiple brands of eReader under one roof, and want to freely share, this should not be an issue ..

I have some 15,000 titles (mostly free), and use Calibre on Ubuntu 11.10 to manage my Kindle 3. I previously used various earlier versions, and on Ubuntu 10.04 LTS.

Note: You have NOT stated what version of Ubuntu you are using, and an older OS (or newer device) may require some additional care & feeding.

Using Calibre with a Kindle 3 on Ubuntu 10.04

UPDATE 20-Aug-2012

Still using Calibre (now v0.8.64), now under Ubuntu 12.04 LTS.

No longer using Kindle 3, gave it to a friend. Now I have two Kindle 4 (non-touch), one for home use the other for work/traveling.

Basically, no issues to report ..

I am the owner of a Kindle and, until a couple of weeks ago, of a Sony Reader. As you explain, and not everyone understood, you can manage both devices with Calibre, but you CAN NOT manage DRM epubs on the Sony unless you use their software (=> Windows). You have to register in Adobe or something like that (actually, I never cared to do it) and it's not possible in Linux.

So your choice is reduced to the Kindle, honestly. First of all, a Kindle is actually a modified Android (it gets recognized as such if you visit certain websites). In addition, I can't think of any Android device with e-ink display.

My advice would be to go for the Kindle. It's a great device for reading, buying from their shop is ridiculously easy and you won't have any problems finding free books for it elsewhere (if you can't find them in .mobi, which is rare, you can convert them with calibre).

I actually bought the Sony in the first place because I was concerned about the EPUB issue, but found out that is almost never an issue.

A lot of time has passed since this question was asked, but I think that it's worth adding that as of today, both Barnes and Noble's Nooks and Kobo's ereaders allow you to purchase content without going through your computer, not just the Amazon Kindles. I've used both Kobos and Nooks, and can manage with Ubuntu without any major complaints.

In addition, DRM-unencumbered books can be copied to these devices via USB from Ubuntu as if you were transferring files to any mass storage device.

It appears possible, but complicated, to install the Kobo Desktop via WINE, but the OP didn't appear interested in this.

Maybe it's just me, but I find it difficult to tell what you're asking here.

Kindle-formatted books cannot be read on any other device without breaking the DRM. (Edit: This does not apply to devices that have Kindle apps available to them, such as Android phones/tablets, iPads, and even desktop browsers through Amazon's Cloud Reader. I am referring only to dedicated e-ink eReaders.) And Kindles can't read many other formats (only Amazon's proprietary format and PDF). However, you can get data onto and off of Kindles in Ubuntu.

If you're looking for as much flexibility/portability as possible, you should buy your books in ePub format whenever possible. This format is supported by the widest number of devices (except for maybe PDF or plain text), and is an open standard, although it is frequently protected by DRM.

Booksellers who offer books in the ePub format include Kobo Books and Google eBooks. These can be purchased, downloaded to your PC, and transferred to any device that reads ePub-formatted books.

eReaders that can read the ePub format include the Kobo, the Sony Reader, and the Barnes & Noble Nook, but there are many more. Shop around to see which one suits you best.

In order to get eBooks onto your eReader, you won't necessarily even need to use your PC. Some, like the Kindle and Nook, can be used to purchase eBooks right from the device. Others will require you to upload the eBook to the eReader from your PC. There is a terrific native Linux application for eBook management called Calibre, available in the Ubuntu Software Center, which supports many different eReaders.

In short, regarding your final question ("Is it correct that the Kindle reader the only eInk device that would give Ubuntu users access to commercial ebooks?"), the answer is no.

Not totally sure what you are after but for what it's worth you can download a "Kindle Cloud Reader" App for Chrome and Firefox. I have done this (I do not own a Kindle) and have registered with Amazon and bought and downloaded books to read in this way.

The basic problem for DRM ebooks is that you cannot link a sony ereader to ADE using Ubuntu platform!Until Adobe come up with a linux[?]/Ubuntu based ADE: it is a no go area the only option is to use microsoft for ADE.

Wifi is a solution but you need to be able to access such services and where I live it is non existent ! best Peter
