After a year and a half, product won't work at all.

Summary: I purchased two of these tablets in Nov. 2012 as Christmas presents. They worked for about a year and a half and now neither of them will charge or boot. There is no support from Lenovo other than "take it to an authorized repair center", which there is none anywhere around me. They're basically trash now and I can't return them. My suggestion is to avoid Lenovo products. In the end, they're not worth the savings.
Summary: The S2109 hardware wise is a pretty decent tablet. I owe one and I'm mostly satisfied with the build and functionality. My biggest compliant is the lack of support Lenovo offers its customers. When this tablet was released late last spring Android 4.1 was already available. Lenovo refuses to provide (or address) providing OS support for releasing a Jellybean update. Part of the lure of Android is the incremental updates that Google provides.
Summary: I've only had this tablet for 5 months but so far one had 1 problem with it and that was an update problem. I love my tablet. I highly recommend it.... UPDATE: Now 9 months down the road the tablet freezes up constantly. Can not turn off or move off that screen. Have to let the battery die completely to un-freeze it...then put it charging to restart it... I have just contacted seller... we will see what happens and will update asap if the problem gets fixed...
