So, I just graduated high school and am allowed basically up to about $2400(dad is putting in 2000 and I'm willing to put in 400) in getting a new mac. Here are the options I have been thinking about: base mac book pro with retina display(256 gb), base mac book air 13" and a base i mac 21.5(getting a deal off of bhphotovideo.com so it would be about the same as the mac book pro with retina display), or a 27 inch i mac(baseline) with a 16gb new ipad. Those are the main options I'm juggling. Btw whatever i get would be used for College(papers, research,ect), skyping (lots of it), music, pictures, maybe a couple of movies, and general email/youtube/internet stuff. I will be doing a very minimal amount of video editing. I feel somewhat uncomfortable and limited with the 256gb ssd on the pro, which is kind of the reason for the whole dilemma so any advice would be helpful. Again, skype is definitely a big thing for whatever I get. Also, I know it's kind of early but I'm pretty set on the dental field if that helps. I hope for something that will last me 5-6 years at the least. Any advice would be extremely helpful! Thanks in advance!
