Hello All, I know that tons of threads are already out there, I just wanted to ask my own question to the community. I use SPSS on a regular basis and usually have Word, Excel, and a Browser tab or two open while I work on homework. Am I going to be pushing the capabilities of the new 2015 Retina MacBook with just these few programs open? I really want the portability, but the Core M processor scares me... Any thoughts on how powerful / or not powerful they are? Anybody used one of the new Lenovo Yogas that can attest to the processing power? Thanks for your advice!
