In fairness Ian, Vectorworks are trying to help people with upgrading via VSS. For someone who upgrades every other year, like yourself, 2 years of VSS is cheaper than paying the upgrade when your software is 2 versions behind. Not only that, but VSS provides access to a host of additional benefits including additional libraries and online support/training content. The only downside is that you ay annually in advance rather than 2 years down the line, but this in itself is helpful as it makes budgeting easier and you are not faced with a higher outlay, possibly at a time when cashflow is tight.
