Notion Ink has been secretive about a lot of things. Very close to actually shipping the product the users don’t yet know what are the full 100% features on the tablet. Looks like that wait is over. CrunchGear coaxed Rohan to give away what the secret feature is, and Rohan obliged.
The secret feature on Notion Ink’s Adam is : RADIO. The only tablet to offer that feature. TaDa. I guess the thought comes from the fact that every gadget sold in India have to perform all the functions which are available in lower-priced phones.
