That's the problem your a techie and if your founding a techie company non-MS solutions will work. But if your running a business that's not techinical think insurance agency, mortgage company, etc. You would go down to "best buy" buy a couple of windows boxes run your loan officer product on windows and try not to think about technology again. Where I work we have a product that runs java on the server but requires IE as the browser. 5 prod websphere servers 700 windows boxes for the users. On the development boxes we run tomcat but if there's a production issues they want to be able to call microsoft or IBM.Also, your going to train 700 users to use linux on the desktop. Besides can you lease linuxs boxes from Dell?
