It's hybrid Set Top Box and its wrong to compare it with DVR Box.
I do not see need of fancy and costly DVR when almost everything is available on internet and we can watch on Internet TV Box later on any time.
Catch Up TV which I am sure Airtel is going to provide, will further eliminate requirement to record any programme on local hard disk when we can pause and rewind any programme.
Also please note that purchasing another Android Box meaning another remote and requirement of another HDMI port. Here with single box and remote we can organise our DTH, local Pen drive files, OTT apps, games, mirroring and lot more things on one single interface.
I was planning to purchase a Chromecast for my TV, now almost for same price I will upgrade my STB to Android TV itself.
In the future we are going to see more Internet Only channels and a Hybrid Box can organise satellite and Internet channels at one place for me.
Also with 500+ channels, who is going to remember channel numbers, here is voice search to select my favourite channel and programme.
When I compare it with my existing HD+ Box as an aam user, I feel it's worth it to upgrade.
