Smart LED Home Theater vs. Samsung LCD TV

Hi all,

Since I moved to a new house, I want to buy a bigger TV. I was hesitated between a Smart LED projector from XGIMI and LCD TV from Samsung. I've heard XGIMI from Indiegogo, and their newest product named Z4 Aurora. However, I never bought a projector as a "TV." They describe Z4 Aurora has built-in Harman/kardon stereo, using Android OS, has 700Ansi Lumen, and can project from 40-300 inches.
Their prices are kinda similar, it's all about $600.
I'm currently concerning:
1. if I buy Samsung LCD TV, I still need to pay extra money for monthly TV box.
2. I never used or knew anyone who's using LED projector. It's too new for me. I'd like to hear more voices from different users.

Thanks a lot!!!
