User Reviews 1 User Reviews I found the Lenovo IdeaPad Tablet K1 to have a solid overall build quality. The 10.1-inch LCD screen displayed good color reproduction and contrast, with decent viewing angles. The rubberized back finish resisted fingerprints well and provided a nice tacky, non-skid grip.
We appreciated the multiple color options available from Lenovo, especially the glossy red back panel. The black rubberized finish was my personal favorite though. It does add some thickness and weight compared to rivals, but provides durability.

User Reviews 2 We would only recommend this tablet for shoppers who are very familiar with Android and can remove unwanted applications. For novice Android users, the extra software may prove too confusing. While the Lenovo branding implies good quality, the software issues outweigh the decent hardware for us. More experienced tablet shoppers who don't mind tweaking the interface would likely be happier with the Lenovo IdeaPad K1.

User Reviews 3 The Lenovo IdeaPad K1 had some nice customizations from Lenovo, like the launcher, app wheel, and social aggregator that made the interface easier to use. The tablet also booted up and woke from sleep very quickly. Battery life was decent at 8+ hours for light usage.
However, I was disappointed by some of the hardware decisions, like proprietary cables and the need for a tool to access the microSD slot. The screen was also inconsistent in responsiveness. We noticed occasional sluggishness and freezing despite the fast processor.

Lenovo has entered the increasingly competitive tablet market with the IdeaPad K1, a mid-range Android 3.1 device. The K1 sports a unique design and custom software enhancements, but suffers from some hardware and performance compromises.

Light and Portable for On-the-Go Use

In the crowded tablet market of 2011, the Lenovo IdeaPad K1 stood out with its 10.1-inch display and Android 3.1 operating system.

Released in July 2011, the tablet garnered attention for its diverse color options, including sleek black and glossy red.

With a weight of 750g and dimensions measuring 264 x 189 x 13.3 mm, the K1 presented a solid, albeit slightly bulky, device.

Decent Specs, But Lacking in Some Areas

Powered by a 1 GHz Nvidia Tegra 2 dual-core processor and 1 GB of RAM, the tablet delivers a smooth experience for games, videos and other apps.

However, the low-res 800 x 1280 screen underwhelms, with poor viewing angles. Shoppers also give up conveniences like a full-size USB port and micro HDMI output.

Lenovo Enhances Software Usability

Where the K1 shines brightest is its Android software. Lenovo tweaks the interface with an app launcher wheel and centralized app menu. This simplifies accessing frequently-used programs.

Despite these strengths, the K1 faced criticism for its pre-loaded software. The abundance of repetitive and confusing applications, along with some functionality issues, affected stability and user experience.

Novice Android users might find the software overwhelming, offsetting the tablet's decent hardware qualities.

The tablet's battery life, reaching up to 10 hours for multimedia use, offered a satisfactory usage time. Lenovo's additional features, such as the social aggregator and quick access controls, contributed positively to the overall user experience.

Performance and Hardware Issues Persist

Despite its fast processor, testers experienced occasional system stutters and hesitations. The inconsistent touchscreen responsiveness also frustrated some users.

Proprietary charging cables and the need for a special tool to access external storage add further inconvenience.


In conclusion, the Lenovo IdeaPad K1 tablet presented a mix of commendable features and notable drawbacks. Its diverse color options, robust build, and Lenovo's software tweaks attracted attention.

However, the intrusive pre-loaded software, occasional performance hiccups, and hardware choices left room for improvement
