At the moment, the UK Government can barely afford a sandwich and a cup of tea, let alone a major IT upgrade.<p>When support eventually runs out then the benefits of switching will clearly outweigh the costs, but at a time when we're talking about reducing the number of MPs and selling off whole government departments, I can't blame them. Maybe the last government could have averted this, maybe not, but at the moment we're such deep economic shit that it's just not a priority.<p>(disclosure: I voted Tory, I hate IE, I enjoy both sandwiches and tea)
