Shouldn’t there be some sort of law about keeping IT out of MPs’ hands? What we to do about a group of people whose every step into the IT word is greeted with laughter and contempt.

The announcement that MPs are rejecting Windows 7 in favour shows us two things; that MPs will routinely plumpfor the wrong one and second, that for all the fine talk about the use of Open Source software, any time that there’s a new contract to be negotiated for a government-run computer system, proprietary software wins out every time.

We have to be realistic here: it was never likely that MPs would opt for an open-source operating system for the House of Commons’ own machines - much as the idea of them searching round for an open-source package to keep track of their expenses has a certain appeal - the choice of Vista is frankly bizarre.

Here’s an operating system that even Microsoft admits was not all it should have been

In part,. Windows 7 was an attempt to address some of those concerns. And, what's more, Windows 7 has been a success, gathering many positive reviews, instead of the universal thumbs-down for Vista . The MPs’ excuse that there’s been time to prepare an assessment of Windows 7 is a load of old cobblers - the software was officially released four months ago (although a workable beta was available some months before that) - just how long do they want? After all, this is not a major transformational project but an upgrade of operating system

MPs are often accused of being out of touch - sometimes unfairly - but to opt for a operating system that was launched more than three years ago, when there’s a more recent (and better) alternative smacks not of a divorce from reality but sheer stupidity.

At least the episode has given us a glimmer of the type of thinking that has bedevilled virtually every major government thinking - perhaps, we should keep MPs away from computers in the same way that we keep children from matches. The consequences of letting either group have their way are too fearful.
