Agreed, the R7 Plus (and R7) looks gorgeous, and a strong contender all-round but for one thing - a rear-facing speaker in 2015, really?
I get that some think that using the speakers for media is selfish, and it would be on public transport I suppose*, but you know what's worse - having a speaker that points at everyone except the viewer. I mean even Samsung have stopped doing it!
* Not all of us use public transport, and for a sneaky Youtube video at home while the wife is watching random crap on the box, front-facing speakers are good, OK.
