Hey Everyone, You can see from my devices listed in my signature, that I just recently purchased an iPad Pro. Love it! However, I miss the laptop form factor for certain things. I recently sold my Aluminum Late 2008 Macbook when I got my iPad Pro. I was due for a new laptop anyway, as the battery only lasted about 90 minutes. Here is my concern. I had the 13 inch macbook unibody (first one). I'm debating whether or not to go for the 13 inch pro, 12 inch retina macbook, or even the 15 inch pro. When was the last update to both macbook pros? I would like to go big again and get a 15 inch pro, but don't wanna be outdated in 6 months. My uses for my computers are as follows: web browsing email ms office and iWork applications youtube/video imovie iTunes Sibelius (for arranging music for drumcorps, marching bands, and percussion ensembles) Will the 12 inch retina macbook handle this? is it better to get the 13 or 15 inch pro? Should I wait altogether? I don't know. I like the air form factor too, but wish it came in a 15 inch model. I don't know... Advice please? And thanks so much!
