Be clear with your question. Your OP simply states "What's the point of getting a Macbook Pro?". If you intended to ask "...versus the Macbook Air" then ask that question rather than assuming that people know what you're thinking.
As for the point, the point is always highly subjective. For me, I didn't want to put up with the limitations of the Air. Obviously, YMMV. Supply your needs/wants if you want recommendations relevant to you unless your goal is just to poll people.
The OP starts off like a typical troll. It's not surprising to me that people assumed that the OP was a troll for asking why anyone would buy a Macbook Pro given that there are Windows laptops that have similar styling. Anyone shopping for a machine needs to look past the photos.
Irrelevant. I'm not an Apple sales rep.
Close but not quite. Microsoft doesn't design their OS's for the various manufacturers and all their products. The OS is hardware abstracted. Manufacturers supply the appropriate drivers and ensure that they meet standards. Even so, as you attempt to point out, that can cause issues as hardware and software are not as closely aligned as they would be when the same company produces both the hardware and software. In any case, this isn't relevant to the OP either.
The OP's trollish intro is what everyone's fixated on. The OP is really asking about comparing the Air to the MBP.
"As long as" is the big caveat. Even you state that not all notebooks ships with decent drivers. It's really a matter of preference. For some, it doesn't matter. For others, it does. Never assume that your preferences are universal.
You haven't been paying attention to new and upcoming products.
