Reviews Word on the street for the Lenovo IdeaPad K1

The LED backlit LCD is decent but not super impressive: sharpness is good enough for reading, but the 250 nits of brightness won't combat outdoor light and it isn't nearly as bright as the Kindle Fire that has the same resolution.

Unfortunately, the competition has already proven that display quality matters to consumers, even at the expense of cameras, GPS, Bluetooth, and even storage capacity.

On a better note, the K1′s battery life is pretty admirable.

When you have the IdeaPad on its own, you won't necessarily notice that the 10.1-inch display isn't very bright, but place it next to an iPad 2 and it becomes immediately obvious.

What People Are Saying Give it to me straight


Lenovo includes their widget for quick access to the web browser, settings and the video, email, music and ebook apps of your choice, and we like it quite well.
by MobileTechReview (Feb, 2012)
The standard Google apps are on board including the Android Market, Gmail, email, the Webkit web browser and YouTube Player.

A downward swipe on the button will back you out of apps or menus.

Lenovo says the panel has a good 700:1 contrast ratio, and it supports 2 points of multi-touch.

If you can look past the mediocre screen quality, the Lenovo IdeaPad A1 is one of the best tablet values around.

The screen quality on the Lenovo IdeaPad A1 tablet isn't great.

Operating system

Sure, Amazon and B&N each offer a dual purpose LCD ebook reader/limited function Android tablet, but they lack the cameras, GPS and full access to the OS experience and Android Market for apps.

Now Lenovo is here with their IdeaPad K1 and ThinkPad Android tablets.
by MobileTechReview (Aug, 2011)
Forget about waiting for Android OS 4.0 Ice Cream Sandwich, this little guy won't even get 3.2 Honeycomb according to Lenovo.

There's no HDMI out, but with a single core CPU and 512 megs of RAM, this tablet doesn't play 1080p video.
by MobileTechReview (Feb, 2012)
The tablet has a 3.5mm headphone jack up top, sculpted volume buttons on the side and a microSD card slot under a cover on the bottom edge (when held in portrait mode).
by MobileTechReview (Feb, 2012)
It has a microSD card slot, a micro HDMI port and runs Android 3.1 out of the box.
by MobileTechReview (Aug, 2011)


The A1 has a 1 cell, 3550 mAh Lithium Ion battery that Lenovo claims is good for up to 7 hours of use when web browsing over WiFi.
by MobileTechReview (Feb, 2012)
