Price Comparison
The Bigme B7 Color is priced at $289.00, while the Kobo Libra Colour is available for $229.99, making the Kobo about 17% cheaper than the Bigme. This price difference of approximately $59 highlights a significant consideration for budget-conscious consumers. The Bigme B7's higher price may be justified by its multifaceted features, including 4G connectivity and calling capabilities, which are not present in the Kobo. However, if you're primarily looking for a dedicated e-reader without the added functionalities, the Kobo may offer better value for your money.
Display Technology
The Bigme B7 Color features a 7-inch Color ePaper display, while the Kobo Libra Colour boasts a 7-inch Glare-Free Colour E Ink Kaleido™ 3 display. Both displays aim to provide a pleasant reading experience, but the Kobo's E Ink technology is specifically designed to minimize glare, making it easier to read in bright sunlight. The Bigme's color display is ideal for viewing vibrant content like comics and illustrations. However, the Kobo's technology may appeal more to traditional readers who prioritize text clarity and comfort over color vibrancy.
Connectivity Features
The Bigme B7 Color stands out with its built-in 4G connectivity and calling support. This feature allows users to browse the web, use apps, and make voice calls without relying on Wi-Fi. In contrast, the Kobo Libra Colour lacks mobile connectivity and focuses solely on e-reading. If you need a device that combines e-reading with additional functionality, the Bigme offers a compelling all-in-one solution. However, for those who merely want a reliable e-reader, the Kobo delivers a straightforward experience without the complexities of additional features.
Storage Capacity
In terms of storage, the Bigme B7 Color comes with 128GB of internal space, expandable via microSD, compared to the Kobo Libra Colour’s 32GB. This provides a substantial advantage for the Bigme, allowing users to store thousands of eBooks and other media without worrying about running out of space. The Kobo can hold up to 24,000 eBooks or 150 audiobooks, which is considerable, but the Bigme's higher capacity is especially beneficial for users with extensive libraries or those who prefer to download content in bulk.
Battery Life
The Bigme B7 Color features a 3000 mAh battery, while the Kobo Libra Colour is designed for weeks of battery life, though specific mAh figures are not provided. The Kobo's battery life is a key selling point, particularly for avid readers who do not want to frequently recharge their device. If you're looking for a device that can last through long reading sessions or extended periods without access to a charger, the Kobo may have the edge. However, the Bigme's battery capacity suggests it is also designed for ample use, albeit with potentially more frequent recharging.
Design and Ergonomics
Both the Bigme B7 Color and the Kobo Libra Colour boast user-friendly designs, but they cater to different preferences. The Bigme features an all-in-one tablet design, which may appeal to users who appreciate versatility in their devices. In contrast, the Kobo Libra is ergonomically designed with page-turn buttons and customizable screen rotation, making it comfortable for long reading sessions. The Kobo's lightweight design is also a plus for users looking for portability, while the Bigme provides a more robust tablet experience for those who need additional functionalities.
Additional Features
The Bigme B7 Color offers unique features such as real-time meeting recording and voice-to-text transcription in 36 languages, making it a practical choice for international users or professionals. It also includes support for a magnetic stylus, enhancing productivity through note-taking and document annotation. On the other hand, the Kobo Libra Colour supports audiobooks and comes with a Dark Mode option, making it versatile for different reading environments. The Kobo also emphasizes environmental sustainability with its construction from recycled and ocean-bound plastic, appealing to eco-conscious consumers.
Which should you buy?
Ultimately, your choice between the Bigme B7 Color and the Kobo Libra Colour will depend on your specific needs and preferences. If you are looking for a multifunctional device that combines e-reading with tablet capabilities and extensive storage, the Bigme is a solid option despite its higher price. However, if you prefer a dedicated e-reader that is lighter, more economical, and offers excellent battery life, the Kobo is the better choice. With its lower price, the Kobo provides a great reading experience and a host of features tailored to book lovers, making it an excellent investment for avid readers.
