I'd like to see what this 'wide range of devices' is. Because this is cloud computing, it shouldn't matter what device you use to access it. I have a funny feeling however that to access this cloud, Northgate will be requiring schools to buy access licences for devices connecting to it. Or some other asshattery that will cripple schools budgets.
They have also been green lighted as a 'prefferred supplier' which means the Education boards think its just fine and dandy that Northgate can slap a 100% mark-up on any item they sell to schools. Fantastic.
