Hi guys, I'm currently looking to splash out on a mac and not sure which one to go for. My budget is £1300 but the less i spend the better. My needs aren't anything drastic. I am a lecturer so design a lot of powerpoints, I also do a fair amount of video editing for YouTube (nothing major, videos tend to be under 10 mins), but I'll edit and upload a few videos a week. I want a 13" because I travel 90 mins to work via train and need my laptop. I'm undecided whether to go for; 1) MacBook Pro regular version - 13", i7 processor, 8GB RAM, 750GB Hard drive, HD graphics 4000 - £1249 2) MacBook Pro retina version - 13", i5 processor, 8GB RAM, 128GB flash storage, HD graphics 4000 - £1249 3) MacBook Air - 13", i5 processor, 8GB RAM, 128GB flash storage, HD graphics 5000 - £1029 Any advice or other recommendations please share!
