The big question is if purchased today does CS 2.3 Premium upgrade to CS 3 Design Premium?
I'm not sure. I didn't actually take them up on their/Adobe's offer as generous as it sounds.
I haven't got time to mess around with 2 lots of ordering; the paperwork and invoices in getting things sorted through our finance dept and budget signoff are ridiculously tortuous. I also have to submit our serials to IT and FAST (Federation Against Software Theft) as well so I just want to keep things simple.
We'll just get 4 licenses of CS3 Design Standard or Premium when UK prices are released, upgraded from CS1... I'm hoping we can stretch to Premium if I can; I budgeted £325 each at academic prices and that can be stretched if necessary. We're a registered charity so get edu prices.
