In reality, Apple seems to be ok with releasing new software once it runs fast enough on current hardware. So it might not run that great on old hardware. That's how progress is made but means it might not make much sense to upgrade. My iPhone 4 is definitely pokier on iOS 5 than it was on iOS 4.
Google+ is dead, just like Ping is dead. The "plus" is just a social network on top of Google products. Ping is a social network on top of iTunes and we know how well that went. People don't like "antisocial" social networks.
The bevel could be virtual - painted on by the OS or application but not accepting touch inputs. Perhaps even custom to the user preferences. It could go away for certain uses cases, like full screen video. It could even have function buttons rendered on it that are context dependent.
Sure, this might work. But the extra pixels needed for the bezel will consume battery with current technology. Also, a new kind of proximity sensor have to be developed for these use cases. It will be really annoying to set the virtual bezel manually all the time.
Photographs and magazines are full-bleed, but we don't mind it. As long as the device is smart about ignoring perimeter touches, I wouldn't be surprised if in the future our phones are full bleed with speakers and cameras hidden behind the display.
I think more aptly, if Facebook buys RIM they're screwed.
It's just crazy talk. Facebook has a headcount of 3,500, and people seriously think they can feasible buy out RIM, with 17,500 people, and then just magically integrate them and poof produce a great phone? It's madness.
If you take the article at face value, Facebook have already tried developing their own hardware and had it implode due to a lack of experience. So for the author to seriously suggest the solution should be to acquire HTC or RIM when Facebook have equally little experience doing large mergers and acquisitions makes no sense to me.
TBH, if Facebook was serious about producing their own phone, buying RIM and letting it operate as a subsidiary would be a wise move.
RIM/QNX make great hardware and (now) software. No one would disagree that they need help on the user experience side of things. They've made great strides in this area too, but that's where Facebook can help. RIM can stick to what it's good at.
