It's a pretty ignorant criticism to complain that Apple doesn't do enough B2B, that's like complaining General Electric doesn't do enough pharmaceuticals--it's not even in Apple's business scope to worry about B2B, they make consumer and prosumer products. I treat idiots with the respect they deserve.
You get my point thought regardless of the example, Oracle doesn't make phones, and Samsung doesn't make game consoles.
Here is a quote from Jobs: People think focus means saying yes to the thing you’ve got to focus on. But that’s not what it means at all. It means saying no to the hundred other good ideas that there are. You have to pick carefully.
And can you give an example and cite how Apple tried and failed to enter B2B?
I am not saying Apple isn't doing well, just that they are great at consumer products but "meh" at business products. That is not a problem though. They are great a consumer products and I admire their ability to release a product without what would be essential features to others because they are not satisfied with it. For example, cut and paste was missing from the iPhone until v3.0.
Apple is great a certain things and at deciding to focus on those areas, such as dropping XServe and WebObjects.
