Saas is digial slavery. For your wallet at least.
Maybe that is a bit dramatic, but I really don't like the push for web serviced software and saas. I've had many products that I have bought once and used for years and years. No additional fees. There is a push to remove that model. Along with it goes the gathering of information. Make an MS account to handle your licensing. . . Give us all your personal info etc. I like to grab something off the shelf and no one needs my life story and all my personal info before I purchase.
