Why not a PC "front end"? Because they tend to look Heath Robinson at best in an AV set-up, the user interface can more often than not suck, it's overly complicated when you simply want to stream iTunes stuff...
Depends on the situation. I use iTunes before on my pc to stream music..not complicated on pc anymore than a Mac. All boils down to the program you use.
I thought about apple tv but just another thing to tie into other things. Again some people it works, others it doesn't.
I wouldn't be surprised if once I get my hp all in one touchscreen installed in a coffee table, I bought an hp slate to control it for use on other TVs or speakers in other rooms. Unless I can get the iPad to do it with ease.
So what exactly can apple tv do? Because I must have missed something somewhere..
