Agreeing with Jason, here. If you only need a computer for basic stuff, like word processing or watching videos, then you should be fine with a Chromebook. But if your business needs to do other stuff-- well, maybe only have a Chromebook for travel or something.
My company is in the web software development business. We've gone from having a room full of servers to none at all in about 2 years. Everybody has a laptop, most of our corporate apps are cloud services or running on Amazon ec2 machines. We save quite a bit on Microsoft tax now.
