Have you been contacted by any DS representative or re-seller? I haven't been myself. Weird it is when I took myself the decision to NOT purchase anymore updates in due concertation with DS representatives. A close look at my business model showing that RoI were simply nonexistent. DS shld understand that keeping a cross-functioning system updated every year (multiple CAD/CAE/CFD) is hardly something that keep returning benefits unless you can assign dedicated time and resources. Especially when Solidworks is proud to claim the largest base of users openly irrespective of their license policy!
No I haven't been contacted, and I agree with your other points about the value for money from upgrading. Maybe if you are lucky there may be a couple of useful extra features....barely justifying the install time let alone the upgrade cost. Alan
