My colleague Jim Morrish has also started blogging and I recommend you take a look. He'll be covering the same sorts of stuff as me, with a particular focus on M2M. Cheekily he's called the blog "Not Quite 50bn" in reference to Ericsson's oft-quoted figure for number of connections by the end of 2020. We're currently putting together our own estimate of the total number of connections. Rest assured we'll be telling everyone about it once we've finished it.
