A number of companies ranging from a Chinese OEM to Wiltronic to RCA showed off Android tablets that doubled as portable tvs. They have retractable antennas, apps which work with the integrated tv tuners, and (in a couple cases) kickstands to prop up the tablet.
Some of the models looked to have decent specs, but not all. For example, the 8" RCA tv\tablet (which was launched at CES 2013) runs Android 4.0 Jelly Bean on a single-core 1GHz CPU. It has a decent screen resolutions (1024 x 768), 2 cameras, Wifi, and Google Play, but I'm not sure that the specs for this tablet justify the $199 price tag (Amazon).
This tablet was just one of several tv tablets that RCA had in display; all could function as Android tablets and only doubled as tvs when you ran the Dyle app or engage the tv tuner app.
I don't see what market these tablets would have, but I could be wrong; The Chinese OEM I spoke to indicated that they were building tv tablets for the Brazilian market, not the US, and that suggests that someone is buying them.
And I would hope that there is a market, because otherwise I don't see an explanation for so many companies building so many models (each company had 3 or 4 different models on display). But to be perfectly honest I think this idea is going to be about as popular as 4G tablets - which are a minority of the tablets sold in the US.
But even though tv\Android is a niche market, I'm beginning to realize that lots of companies are dabbling in it. Even Samsung, for example, released a smartphone in 2012 that offered free digital TV.
