re: 6 Features I Want In Future Smartphones
Very good points... I would personally like to see a phone that stops actively seeking signal (and using battery life) after it's lost signal for a number of minutes. As it is, I've learned that commuting in the NYC subway that my battery lasts a lot longer if the device is still not actively searching for signal all the time (especially since there's little/none to be had underground, in most places).
I think multiple personalities will come as soon as virtualization on the handset occurs - one VM for business, one VM for personal. Or, maybe not in the form of VMs, but running each personality on a core of the device's CPU.
A nano-phone sounds like a good idea - as far as implementation goes, I can see something about 1/2 the size of the average smart phone with a very limited app selection acting as a remote to connect back to the primary phone. Set up a VPN link between the two to secure the data flowing between then and voila. We can already use our smartphones as remote controls for our home theater and cable systems, so why not?
Power management is a great idea, but then you wouldn't have things like Apple's hand-warmer feature on the iPad 3. The more circuits you stuff into a smaller device in order to make it go faster, the more juice it's going to take. Now, if the phone could power down sections of hardware that it wasn't using in order to conserve power, that would be a cool idea.
Social/physical awareness is coming - it's just a matter of time. That's one of the things that Google's working on with regards to correlating all of our personal data/habits and creating an enlightened device. That could be the one feature that sets Google+ apart from everything else once it gets rolled into the product.
