Well I dished out for a new macbook pro. The one with the touch panel. Looking forward to playing with it (in 3 or 4 weeks). I normally do my development work on one of my many Mac Mini's or my trusty 11" Macbook Air. It is truly amazing how long that Macbook Air worked. It had a 5 year old processor and only 4 GB of ram yet it would allow me to run Xcode, simulators, Safari etc, all concurrently without any problem. I did the majority of my IOS apps with it. I was only slowed down occasionally by the small screen, but it worked well and was extremely portable, and looked (still does) beautiful. My main reason for the new computer is that the battery seems to be nearing the end of its life on the air, surviving only an hour on a full charge. Tuire has an iPad retina, the twins have their iPad mini's (in big shock cases) but I am sure that I will find a use for the poor old guy though!
As for the lack of old school USB on the Pro, I rarely ever have my Air connected to anything other than Wifi to my network, so it's perfect for me. I may get a small cheap dongle hub if required. For the curious I took the basic 13" touch panel model but maxed up the ram to 8GB. For future proofing, you always should max up the RAM as it is not user upgradeable.
