Introduction: A Tale of Two E-Readers
This is a head-to-head comparison between the newer Bigme B7 Color and its predecessor, the Bigme B751C. Both devices feature Kaleido 3 color e-ink displays, but they offer vastly different user experiences. This comparison reveals more than just a generational upgrade; it highlights the critical difference between a modern, supported device and a predecessor left behind by software updates. This article provides a detailed analysis of their displays, build quality, and performance to help you decide which e-reader is the better purchase today.
1. Display Quality: Clarity, Color, and Glare
The visual experience is paramount for an e-reader, and it's here that the differences between the two devices become immediately apparent.
Screen Finish and Reflections While the older B751C may occasionally show slightly more color saturation on specific images, it suffers from significantly more glare and reflections than the Bigme B7 Color. This makes the B7 Color easier and more comfortable to view in various lighting conditions.
Brightness and Whiteness The core difference lies in the display's tone and brightness. The Bigme B7 Color features a much whiter, brighter, and "crispy" display that looks like real paper, particularly when the front light is on. In contrast, the B751C's screen is darker without illumination and appears more yellowish and less bright when the front light is activated.
Warm Light Comparison The B7 Color's warm light is brighter and delivers what is described as a "really nice optimized warm color." In one specific scenario, however, the B751C holds its own: when using only the warm light, its display is considered "quite good," producing excellent colors.
2. Build, Design, and Ergonomics
The physical construction and feel of these devices are worlds apart, signaling a significant evolution in design from one generation to the next.
Materials and Feel The Bigme B7 Color has a "much, much nicer" feel and a superior build quality. The B751C, on the other hand, is described as feeling "very very plastic" and "plasticky." The source material notes that the plastic on the B751C's charging port had even broken. This specific point of failure underscores the broader concerns about the device's long-term durability compared to its successor.
Physical Buttons The tactile feedback from the page-turn buttons also differs. The buttons on the B751C feel "sloppier" and less refined, while the B7 Color offers a higher-quality mechanism with a more satisfying and "distinct" click.
Form Factor and Weight The older B751C is "a lot thicker" than the more streamlined B7 Color. While their weights are about the same, the B7 Color is noted as being "maybe a bit too heavy," which could be a factor for users who have problems "with holding it for a longer time."
3. Performance and Software Experience
While physical differences are immediately apparent, the chasm in long-term usability is defined by software and performance, where the B7 Color's modernity renders the B751C obsolete.
User Interface (UI) and Updates The B7 Color runs a "lot more modern" user interface. Critically, the B751C no longer receives software updates, leaving it with an outdated interface that includes a permanent bar with buttons at the bottom of the screen. This isn't merely a cosmetic issue; the outdated interface points to a complete halt in development, impacting everything from usability to security.
Scrolling and Refresh Speed Performance is a major win for the newer model. The B7 Color's scrolling is described as "really, really, really fast," feeling almost like an "LCD tablet." The B751C is "very much slower" in comparison.
Ghosting The Bigme B7 Color features a very effective "automatic ghost removal" that works "really really nice." The B751C exhibits "a lot more ghosting" when using its fast refresh mode. This is a direct consequence of its abandoned software, which lacks the more sophisticated ghosting-cancellation algorithms found in the B7 Color.
4. Head-to-Head Feature Comparison
This table summarizes the key differences between the two models.
Feature | Bigme B7 Color | Bigme B751C |
|---|---|---|
Display Tone | Whiter, brighter, and paper-like | Darker, more yellowish |
Glare | Less glare | More glare and reflections |
Build Quality | Superior feel | Feels "very plastic" |
Buttons | High quality, distinct click | "Sloppier" |
Software UI | Modern, updated | Older, no longer updated |
Scrolling Speed | Very fast, LCD-like | Much slower |
Ghosting Control | Excellent auto-ghosting removal | Noticeable ghosting issues |
Thickness | Thinner | A lot thicker |
Battery Life | About the same | About the same |
5. Final Verdict: The Clear Winner
Based on this direct comparison, the recommendation is unequivocal: the Bigme B7 Color is highly recommended over the Bigme B751C.
While the reviewer notes being "quite impressed" with the B751C's performance for its age, this doesn't change the final recommendation. The B7 Color is superior in nearly every meaningful way, stemming from several key advantages:
• Modern Software: The B7 Color features a modern UI and the potential for future updates, while the B751C is stuck on older, abandoned software. This is the root cause of its other performance failings.
• Better Performance: It offers significantly faster scrolling and much more effective ghosting management, creating a smoother, more modern user experience.
• Superior Display: The B7 Color's screen is whiter, brighter, less reflective, and more closely resembles real paper.
• Premium Build Quality: The device simply feels much nicer, more modern, and more durable in the hand.
• Future-Proof Features: As a more modern device, the B7 Color handles modern tasks like "sharing options a lot better and you can use AI better."
For anyone choosing between these two e-readers today, the Bigme B7 Color is the definitively better and more future-proof option.
