I always find it amusing when someone tells me that, because I don't need an ODD or ethernet, a Macbook Air would satisfy my needs. I can't express how asinine that is.
If anything, I hope that this demonstrates how asinine both arguments are; the fact of the matter is that most of the people on here wanting a machine without an optical drive and Ethernet, don't really have a use for any other MacBook Pro feature other than the larger screen sizes. For those that do have uses for such a hybrid of the two lines as they currently stand today, they are in the minority; which doesn't make their wants and/or needs invalid, just unlikely to be served by Apple. Stupid really, they should have more options.
Or, we can have a thinner, lighter MacBook Pro, complete with high-res display and dedicated GPU and plug in an external Ethernet adapter and ODD.
Come on Knight, this is so unlike you. You know that won't fly logically. Dedicated GPUs require space in all dimensions. Plus which magical interface is going to give me full gigabit ethernet? Thunderbolt is impractical and unless USB 3.0 is going to be able to give me that kind of performance through Ethernet (which it very well might; I don't know the speed of USB 3 off the top of my head), I don't see where a dongle is going to help me out here.
