Hi all, I thought I would ask for some advice, as this is clearly the best place to ask; I hope you don't mind. I have a 1.3 256gb MB on order (about 3 weeks away) and I think the it's size is perfect. But I'm not the richest of people so I want to buy something that has an element of future-proofing to it. So, my questions: 1) Will the 1.3 struggle to play .MKV files or other 1080p film files? 2) Does the 1.3 really lag or is it just the UI issues currently? 3) I'm considering cancelling and instead ordering the rMBP 13 as there are no issues with processor performance and, hopefully, I'd get 4+ years out of it at least. How many years do you think we will be able to get out of the new MB? 4) Is the rMBP 13 easily portable? Do people carry it around and use it in coffee shops (I tend to see just airs)? Sorry to ask, but I know you will all have far better experience on this than me. FYI - this will be my first Apple computer.
