To what extent is that because of price increases? I used to work in higher ed; I think we were able to negotiate a not-as-heart-attack-inducing increase over what we used to pay for the number of licenses we had, but since leaving there I have no idea if there have been further increases. I know the increase at one school was substantial enough that they threw the Adobe rep off of campus.
I teach Maths and don't make much use of Adobe CS but at one centre I teach in they are hanging onto CS v6 on the network.
The UK student monthly fee for a student for their own use at home is a tad under £16. Probably ok for an undergrad but a little steep for a 16 year old in an FE College who needs access to Illustrator now and again at home...
