Hi everyone, I have a Macbook Pro 13-inch (Late 2011) with the following features: 2,8 GHz Intel Core i7 processor, 750 GB Hard Drive, 4 GB RAM. And I would like to know if it is a good idea to change this Macbook Pro by a current one or maybe change it with a Macbook Air because the Macbook Air is comfortable with the weight. I already have an iMac 27-inch with a 1 TB Hard Drive, 3.2GHz quad-core Intel Core i5 processor. So I don't know if I should change my Macbook or just wait for something better, please leave me your opinion below, thanks
