Like I said, I can see diversification of portfolio as something to gain.

On the other hand, Apple's non-existence in the enterprise space isn't due to a lack of trying. They've been there and done that already.

Apple explicitly failed in the enterprise space because they didn't care. They built a very well-decorated walled-garden, but it's not what enterprise customers wanted. Apple wanted to sell UNIX, the customers wanted to buy servers. When the dust settled, Apple made no attempt to respond to customer demands. They smothered the product with a pillow and told their enterprise partners to pound sand or buy a Trash Can Mac.

Do you mean tried and failed?
