Hi, We need a new laptop as from time to time my wife and I have to bring the computer to work (at the same time) and we leave the other without it. I'm a teacher and I use iPad with a projector but I know there are software so I can use the laptop connected to the projector and with the tablet make annotations on the computer screen (when showing a picture, making a presentation....) besides that laptop use will be documents, internet, movies programming (C, python nothing serious) and sometimes Aperture and little gaming. For all these reasons I think rMPB 13" (8 gb RAM and 256 SSD) will be a good choice as it's only about 100$ more expensive than MBA (same RAM and SSD) in spanish apple store (educational). I can afford rMBP 15" but it would be too much, don't you think so? I've chosen 8 gb RAM, this way I feel confident it will last as my 2007 MacBook I'm also thinking of getting an Apple TV but I've read in the buying's guide in this page that it's better to wait. Or also I've read in this forum in some thread Android TV will be better. I won't use at school cause we have VGA projectors and I want to use the software I mentioned. Besides all of that I want to know your opinion about how printers work with Airprint? I've never used any nor seen any of those working. I consider buying a cheap one. PS: Excuse my English. If I have to provide further explanations I'll be pleased to do so.
