...same goes for SaaS .

I've worked as an extensions developer on SAP for a couple years now. This kind of thing is typical...They sell first, deliver later (if at all). Their business software does everything in theory, but it really doesn't do anything in practice. A standard ERP system costs millions to install (a few million for the software itself, tens or hundreds of millions for the armies of consultants required), and after you're done, you feel like you've somehow taken a big step backwards.

If you think Microsoft puts out crappy products and has shady business practices, give SAP a go and you'll think Microsoft is headed by Mother Teresa.
