Well it's a smarter deisgn I guess, but the battery pack actually makes it look worse than the others. The only people using wireless bars are going to be people with projectors. Can you imagine putting that on your wall with the giant battery pack dangling off the end?
For that matter none of these bars seemed to be designed for projectors which confuses me a bit. You would want the bar to be taller than it is deep so you could easily tape it to your wall/projector screen right?
Luckily I have a center channel speaker mounted just below the projector screen, so I was able to put the wireless bar on top of it. But I agree, they should make them easily wall mountable.
Also, I got my component cable from ebay the other day and it seems to be broken

I'll probably just buy an official nintendo one so I won't have to worry about it not working.
