This week I have been mostly underwhelmed by mobile announcements

The Mobile World Congress in Barcelona usually manages to completely underwhelm me with some pointless announcement or other, and this year has been no exception. Apparently, and I trust you are sitting down for this, dealing with the smartphone-driven network demands for data services is proving something of a challenge. With global mobile broadband subscribers expected to continue rising at a stonking pace, hitting 5 billion or so within five years, the challenge is only likely to get worse.
