Going along with the software doesn't sell problem, supporting software on customers laptops is a nightmare. No two environments are identical, you don't know what weird things they've done, this causes all sorts of new bugs. We don't know how to write bug free software for a reasonable price, and it's a lot easier to debug and update software on a server you control than on a customers computer. On a server no one complains about auto upgrades, on a customer computer there's going to be a lot of people who don't upgrade but still want support, even if you try and force auto upgrades (which will annoy people) someone will have figured out a way to prevent that from happening. --- I think for a lot of companies SAAS is unfortunately the responsible financial decision.
