I have been participate in the my company initiative regarding SaaS. In the beginning i was thinking that this is modern initiative but than realize that this is real benefit for ISV and end users.
Benefits for ISV:
1. Less painful version upgrade
2. More control
3. Fast Feedbacks about use system
4. Less expenses for regression testing
For End Users:
1. Less expenses for IT Stuff
2. Access from anywhere
Good thing that both side has benefits from SaaS and it made us partner :)
