Apple TV, what is it ?

Apple iPhone -

Greetings Bill and Group Members

I have an iPhone 4 as well as an iPad (who doesn't) and wanted to know if anyone had used apple TV with any of these components. I'd also like to know some (if any) of the cool things i could do with an apple tv and my other home equipment which consist of 2 Vizio televisions (55" & 45") and my two 32" inch Vizios usual solely as monitors for my ZT desktop. Thanks for any info you can share .....

iPhone TV
I don’t have an iPad, but I do have an iPhone 4, my MacBook Pro and — since Christmas — an Apple TV. I have been successful in streaming movies, photos and music from the MBP to the Apple TV. I’ve only tried streaming podcasts from my iPhone to the ATV, but that was also successful. I also have Vizio TVs (a 32” and a 19”), and they work just fine with the ATV. :)

I like playing music from computer or iDevice through TV/sound system. Also like to view photos from iPhone on TV
