These Indian branded tablets are quite budget friendly, available for 5K - 15K and ship with significantly good hardware like 1GHz processor, GPU, VPU, 1GB DDR3 RAM and capacitative touch screen and run on Android 4.0 Ice Cream Sandwich. On the innovative front, some of these tablets have a regular USB port for use with external 3G/EVDO dongle.
Micromax Funbook is having good sale, as I believe, the company has quite good popularity, I mean people know about the brand.
But what about Zync (Z990 Plus), Kobian (Mercury mTab Rio), WickedLeaks (Wammy Plus), iBerry (AX01, AX03G) and so many... These companies have few or zero presence in handset market, but entered the field to mark their presence in tablet PC market.
Once-not-so-popular-but-now-a-known-brand Notion Ink did not able to take care of the hype rose for their much-anticipated Adam tablet.
So conclusion is 80% of people are not buying tablets, none of my friends are having tablets, just like less 1% of my friends are using Blackberry :P
Sorry tabbers, you have to wait for another couple of years to get more in your comm. Till then get phablet friends !
