The Three Top Gadgets for Christmas according to CNN:

E-readers

Tech industry analysts say e-readers are going to be one of the hottest gadget categories this holiday season.

Tablet computers

Tablet computers -- also called "slate" computers -- are basically laptops that have had their keyboards removed.

 'Connected' TV

Connected TVs are connected to the internet. They act  like computers with bigger screens than the old televisions, and they let you stream YouTube videos or Netflix movies alongside shows on old-fashioned TV channels.
