Tim Marman responds to my response on software subscriptions:

It's quite obvious why a software company wants to move to a subscription model. The question is whether their software warrants it. The aggregator space is crowded with quality free substitutes, which means that the market is going to be more sensitive to price. (In other words, demand is elastic). If I'm going to pay for something while there are free alternatives, I'm going to have to see real value in it. If I'm going to pay someone on an on-going basis, I'm going to have to see real on-going value in that.

That's all fine, and I understand. The bottom line is this though: Do you want your vendor to stay in business or not? Again, Get a calculator or spreadsheet, and at the $25.00 price, figure out how many new copies need to be sold year after year to support a business. I have no ide how many employees those guys have, but even if it's only a handful, that's a lot of new sales.
