OK, what maker of computers offers a three year warranty which includes any monitor you purchased with the computer and provides up to complete replacement at no charge? That's what AppleCare provides.
If Apple were really pursuing enterprise sales it would have a sales department with many more than 11 reps. The Computer punditry have been crying for years for Apple to become serious about seeking enterprise level customers... and providing the same level of hand-holding that PC IT buyers seem to think they need. Some of the PC companies have more than 11 reps just for one company. Apple, so far, is not targeting the enterprise market. If they were they would be offering iMacs without built-in iSight cameras.
Apple does target high end graphics users and makes some very good offerings in that area with the Mac Pro and the Cinema Displays. They are not consumer computers, but they are not designed for enterprise general use.
I find it funny that you are defending Apple - a premium brand - by comparing it commodity computers. It sort of appears that they aren’t a premium brand - that their hardware is no different than all the other major computer brands.
You leave out a major issue with apple and the enterprise - that little issue of them not having a true server class operating system or any server class hardware.
