USB720 or MI-FI & TV question

[Mamabear4life]

I use a USB720 as my home internet (rural area with no other service).  I currently have the USB720 and it works fine for us, though I may change to a MI-FI at a future date if I determine the need to.

I am trying to determine if the USB720 or the MI-FI can work with streaming movies, etc to a television set.  I'll be purchasing at new television soon and would like to know if this option would be available to me.  Because of our rural area we also have regular no-frills cable, there is no on-demand or pay-per-view available. 

I've streamed thru Amazon and watched movies on my PC thru the mobile broadband, but I'd like to know if I could do it to a TV.  Will it be feasible, and will I need a special type of flat screen TV?  I'd prefer to do it without having the hassle of hooking the computer to it if possible, but if I have to I could hook up the laptop.  Or would an internet ready TV work?  We will probably be looking at approx 37" TV (bedroom). 

Any ideas or suggestions would be appreciated. Thanks a bunch!

I was in a motel last week and used my USB760 to stream a Netflix movie to my computer. I had the computer plugged into a widescreen HDTV and it worked fine. The only problem, I used almost 1 GB to watch one movie. It would not be a viable alternative to cable or satellite tv.
