Well as s/w improvements don't necessarily happen on a yearly basis, but people like being paid each year, I think the model is not unreasonable, as long as the cost is reasonable - which, for instance, the Adobe s/w isn't. As one can tell from the profit margins of s/w companies. So I do pay my Schrodinger PyMol licenses each year.
just my 2c

But being told to re-buy PyMOL annoys me, even though I would renew anyway just to support PyMOL development, and I can compile it just fine. (The expiring XDS binaries are also annoying, but there the software is free and the only purpose of the expiration is to force people to update, which I fully support.)
