I wasn't sure what forum to post this.. but here goes: I bought me a new LCD TV for my livingroom last week. This was my first experience with HDMI which, I must say.. is very cool. Digital video and audio is all routed through one cable. Hookups took 2 minutes. It couldn't get any easier, IMO. However.. I go to connect my TV to my receiver... but, digitally, there's only an optical output on this thing. My PS3 and my U-Verse box are the same way.. optical only. It's not a huge deal other than having to special order an optical cable. (I don't dare buy an over-priced one from Best Buy or, God forbid, Radio Shack... a 10ft cable from RS is like $40.. I can find one online for $6) Now.... this TV purchase has been my only HT-related purchase in the past couple years.. so, admittedly I've been out of the loop somewhat. But, a couple years ago I'd tolerated optical cables thinking it was just a kitchy, flash-in-the-pan HT trend. I'd expected coax to take over the market because it's got to be cheaper to implement on the manufacturing side, the cables are cheaper, and... it's digital, man! There's no difference between digital in light form over digital in electrical form. Is there? WTF? So... to summarize my rant here: Why is optical overtaking the market!?!?
