Mike Lazaridis seems to have been a real grouch at MWC this week as apparently he hasn't stopped talking about the doom and gloom awaiting mobile carriers over the next few years. Focusing on the bandwidth-hungry North American market, Lazaridis has criticized the apparently irresponsible network saturation growth, which he sees as being primarily driven by app-centric operating systems. If you're wondering who he could possibly be referring to, let Mike clarify it -- according to him, you could carry five BlackBerry devices for each iPhone on a network. As evidence of his firm's focus on efficiency, he points us to that freshly demoed WebKit browser, which he claims uses a third of the bandwidth required by the competition from Apple and Google. If only he wasn't implying that owning a BlackBerry would save the internet, Mike's sales pitch would be rather compelling -- those are mighty impressive numbers he is citing.
