    What a load of bullshit! I’m a fan of using web-based apps, but write-ups like this are just complete bollocks. There are so many flaws with your calculations that I don’t have time to list them all, but here are some highlights…

    You indicate that a Dell computer draws 300W of power each hour? Have you ever measured that? An inefficient computer will draw less than 100W, and a modern computer will draw closer to 50W.

    You indicate that if you use on-site software, you have to provide on-site support. That’s nonsense as most support will be done remotely, and the only issues that would require on-site support (hardware issues) would affect you whether you’re using SaaS apps or not.

    Also, there’s nothing stopping you from running a web-based application from an onsite-server, so you’d be able to switch to netbooks if you wanted to. Saying that netbooks can only be used with SaaS services is just plain incompetent.

    And the less-frequent hardware upgrades is not true either – most companies upgrade their hardware to ensure they stay supported with warranties and that applies to whether you’re running desktops or netbooks.
