Lenovo has priced an entry level 7" tablet computer to ensure it is the cheapest on the market. Sure, if you look around hard enough there are tablet computers available for maybe 10 bucks less but the difference is all in the battery. There is no use going for a tablet that has only 2 hours battery life. Our real world usage gets around 6-8 hours of YouTube watching out of one charge. The Lenovo Tab 7 Essential form factor is thing and light and comes loaded with Android 7.0 that can be configured for multi-user accounts. That is if you can spare the storage space for all your apps and media.
