Interoperability between LTE FDD/TDD network
In countries where FDD and TDD are both in use, it would be interesting to see Dual-mode LTE terminals that would support both TDD and FDD and it should be possible to do a reselection as well has handovers from one mode to another.
If you are wondering why we need both FDD and TDD modes in the same geographical location, its because of Spectrum being available as well as with TDD allows possibility of different UL/DL data rates which generally means more efficient use of spectrum.

Shared Data plans anyone?
Shared plans are common in business tariffs but for some reason operators are reluctant to offer them on personal plans. With multiple devices becoming a common place, I would rather prefer to have a single plan that can be used across multiple devices rather than paying for a plan for each device.
From operator point of view, I think they would get a higher loyalty rate if they allow this as it means that if you want to change an operator, you would have to change SIM from multiple devices and some of these devices may be locked to an operator or may not work on other operators, etc.
An Infonetics Research report is embedded below:

Overcapacity or Capacity Crunch?
A Qualcomm presentation from not too long back:
And another report from the UMTS Forum that is suggesting that the data traffic will grow 67 times from 2010 to 2020, summary embedded below:Then I came across this interesting discussion on Twitter and a blog post by Dean Bubley in Disruptive Wireless blog.
Overcapacity has been summarised in few words as: Overcooked forecasts + WiFi offload + optimisation + LTE + more spectrum + caps/tiers + well-designed apps
In the blog post Dean's mentioned about the falling data usage that has been reported by O2. I would strongly recommend reading it.
From the network point of view, I think overcapacity is better for the time being as we are prepared for the short term future. In the long run, new devices and innovative apps may suddenly start driving up the data demand again and hopefully by that time we have sorted out some more of the capacity crunch issues.
What do you think?

Another concept phone from Nokia called 'HumanForm'
Description as follows:
HumanForm was created in a joint effort between Nokia Design and Nokia Research Center to translate the most promising new nanotechnologies into meaningful user experience, prototype those for decision making; and transfer and set aspiration for future portfolio.
Project is a key to bring significant user experience benefits to the market thereby creating mindshare and value share through nanotechnology enabled experiences.
HumanForm is a visionary solution for a dynamically flexible device beyond touch screen and voice communication where technology is invisible and intuition takes over. Natural interactions are enabled with kinetic user interface.
HumanForm concept and a follow-up Nokia Kinetic Device prototype were launched in Nokia World 2011.

Video on the Vision of the Future
I came across couple of videos recently on how User Interface for the future is going to be different than what we are used to. Its already getting changed as we get used to the touch screens and gesture recognition. Here is the first video that came out couple of weeks back and has already had over 2 million hits:
There is a whole blog post dedicated to this which you may be interested in, available here.
Another one is on the gesture recognition that will probably make big on the future devices including TVs.
On a lighter note, the future generation would probably just take the touch and gesture recognition for granted. Here is one such video:

Redirection, Reselection, Handovers and other Inter-RAT combinations in LTE
Another one from Qualcomm's 4G World presentation. You can see the number of scenarios that would have to be taken into account for; this was one of the reasons I believed SVLTE may be a good choice.
