MrClass wroteHtc could have targetted at least the music enthusiasts. Boom speakers, some built in headphone amp, Beats headphones.
Some edge at least.
I agree on the first part because most manufacturers seem to be ignoring the music quality. But not the edge screen, that's really useless, it just makes the phone look good. Functionality wise it adds nothing worthwhile and it makes the screen much more prone to shatters if the device is dropped.
edit: you probably meant 'edge' as in something to give them an edge in the market, just realized that ;)
