Nobody here has heard the speaker on the iPhone Air.Yes I absolutely do. The difference between mono and stereo speakers is night and day mate on an iPhone.
Bluetooth speakers are going to absolutely blow away the sound quality of a mono iPhone speaker. That's an absurd comparison.
As I said, if it sounds like total crap, I'm with you, it does matter.
You are making an assumption that it's going to sound terrible just because it's mono and that's not fair. Maybe Apple decided to use the space for one kick-ass speaker instead of two sub-par speakers? We really don't know.
My point was that mono vs stereo isn't the only deciding factor. If you agree that a mono bluetooth speaker could possibly be acceptable then you should agree that a mono phone could possibly be acceptable as well.
Regardless, we will know in a week.
