After cracking open the box and spending the past 2 weeks working with the new fully loaded Mac pro with retina display, I have to say I'm really disappointed. The my main gripe is with the intergration of the screen and OS. Apple have not revised the OS to display to the capabilities of this screen. The more screen realestate you attempt to gain, the more blurred the image becomes, the quicker I get a head-ache. Putting the screen to (best for Renina) provides no advantage over the standard screen. Spending the extra cash makes me feel that Apples marketing team have just cheated me. My second main problem is with the lack of Ethernet connection. First I didn't realize that the computer did not have this connection port. It still is and has been for the past 10-15 years an industry standard for fast and reliable connectivity to any network. Being a pro labeled computer this should be standard. For my work I require transfer of data that runs into gigs every day. relying on wifi eventually frustrated me to the point of walking out the office and rushing down to the nearest Mac store to spend more money on a device that quite frankly should not be needed. Then I wanted to transfer data from my network to my portable external drives. Something I've been doing for years. To my rage, I then realized, I only have one remaining USB port. How can I connect 2 drives through a standard USB at the same time and have access to my network. It's not possible. As a result; I'm now back on my 2008 Mac pro, not having any headaches and transferring data as required. I'm still frustrated with my old computers screen res, and the new pro is collecting dust in the corner of the room, while I determine if I'm going to return it back to apple or spend more money trying to enable the computer to do what is expected of it. I didnt buy an Air, I bought a Pro, that has the limitations of an Air. Am I angry, yes. Have I lost trust with Apple, yes. Do I feel cheated, yes most defiantly. I'm sure some people will feel different about some of my comments and thats ok. I'm logging these concerns as I think people should know the limitations I've experienced with Apples latest flag ship laptop. I've been an Apple user for years. But I'm convinced apple are now a marketing driven company, with little respect for the users who have adopted their tech and the challenges we face on a daily level. All in its a very disappointing product. This is not innovation, it's misunderstanding what people need. 1 step forward = 3 steps back.
