Hey, these are design concepts. Like concept cars they are meant to imagine the future not to be perfect. A concept is like a brainstorming, first you get the ideas. Details follow later.
The last thing I saw that remotely resembled an interesting "concept design" was when Apple told a bunch of people they were making an iPod phone with multitouch, a full-featured web browser, cover flow, and on-the-fly Youtube access, but that wasn't a concept design, that was a product unveiling, because Apple doesn't do concept designs because Apple thinks they're bullshit as well.
