The hardware isn't a problem...
...nor are the teachers, really. A lot of the time IT teachers are also the network manager, so although they may not be god's gift to either IT or teaching the chances are they know enough about both to teach children about IT.
The problem is the fecking useless syllabus that's been taught in this country for the past 10 (?) years that - as far as I could work out at the time - only teaches people how to be secretaries and admin monkeys. The closest we got to programming with using Frontpage to design a website. My school didn't even offer ICT at GCSE level because it was seen as pointless, and at A-Level they offered the ECDL courses and exams for those who wanted to take them as an additional subject.
Anyone who thinks the decline in ICT skills over the last X number of years can be resolved by a little circuit board with some LEDs is off their bleeding rocker. Rather than cock about with hugely expensive initiatives like this when you could, you know, put it on the syllabus that use one of those dusty old fashioned PC thingymagunks* sat in the corner to teach some fun little Vb projects?
