The Kobo eReader is an e-reader produced by Toronto-based Kobo Inc (a subsidiary of Rakuten). The company's name is an anagram of "book". The original version was released in May 2010 and was marketed as a minimalist alternative to the more expensive e-book readers available at the time. Like most e-readers, the Kobo uses an electronic ink screen.[1] The Arc tablet series, released between 2011 and 2013, was based on LCD technology instead.[2]
All Kobo e-readers share a unique pagination system giving users the option to either count and reference pages separately within each chapter or in the book as a whole. Up until an update in January 2022 Kobo readers required connection to the Internet during the initial setup phase and did not work until they were connected to Kobo's servers; however, they now support "sideload mode", which allows the reader to be used without registering it to a Kobo account,[3] Kobo e-readers support viewing KEPUB (Kobo's proprietary ebook format based on the EPUB format), EPUB, Adobe PDF, plain text, HTML, and unprotected Mobipocket (MOBI, PRC) e-books. Some also support other formats, such as ZIM, unofficially.
The Kobo Elipsa 2E was released on 19 April 2023. It has a 10.3-inch E-Ink display at 1404 x 1872 pixels with a density of 227 ppi, 32 GB of Rom, 2 GHz CPU, WiFi 802.11 ac/b/g/n, Bluetooth, USB-C, and an updated stylus.
The Kobo Clara BW was released in April 2024. It is one of the first Kobo devices marketed as repairable, and the first with a Carta 1300 display. Its accessory covers are compatible with the Kobo Clara Colour.
The Kobo Clara Colour was released in April 2024. It is also marketed as repairable, and has a color Kaleido 3 display. Its accessory covers are compatible with the Kobo Clara BW.
The Kobo Libra Colour was released in April 2024. It is marketed as repairable, with a 7-inch Kaleido 3 display and support for the Kobo Stylus 2 in all applications.
Kobo Inc. announced its first e-reader on 24 March 2010, at the CTIA show.[4] The device was officially released on 1 May 2010.[5] It had expandable memory, holding an additional 4 GB via an SD slot and limited wireless connectivity via Bluetooth to select Blackberry wireless devices. It was available in black or white and came preloaded with 100 public domain books.[1] It was manufactured by Netronix Inc.,[6] a Taiwan based company with factories in Taiwan and China.[7]
The pricing strategy of the original Kobo, at US$149, was to rival the Amazon Kindle, which was US$110 more expensive. However, in June 2010, just after the Kobo was released, Amazon dropped the price of the Kindle to US$189.[8] Its pricing strategy in Australia was similarly aggressive where it was available for A$199, again A$100 less than the Kindle.[9] Borders Australia said that they hoped to sell high volumes of the Kobo to drive up sales at their e-content store.
The original Kobo received a mediocre review from CNET, which said that, while the Kobo was compact, lightweight and affordable, the lack of Wi-Fi or 3G made it outdated, especially when there were similarly priced eReaders available with those features.
In December 2010, the original Kobo's feature set was updated with a firmware update to more closely match the Wifi model.[10]
A new model with Wi-Fi capability was released on 15 October 2010. It included an improved processor, screen, and new colour choices (porcelain/metallic silver, porcelain/pearlized lilac, and onyx). The SD expansion had been improved to claim a capacity for up to 10,000 books with a 32 GB SD card.[11] Other improvements included a longer battery life and a built-in dictionary.[12]
Like the original model, the Wi-Fi model came pre-loaded with 100 public domain books.
