Should I buy a 13 or 15 inch MacBook Pro? Well, I will be using it for three main purposes: a) iWork + Office b) iTunes c) Chrome Browser I have thought about three factors which will determine my decision... 1. Specs: Aiming to use MBP for at least next 5 years. Will I regret getting 13' because it has integrated graphics, and from previous experiences, I feel dedicated GPU even makes browsing experience and UI animations in Windows much more smoother (more pleasing for eyes at least), at least on Windows but I don't know if this is case on OSX. 2. Speakers: Heard there are differences in speakers between 13' and 15' versions. Is it wiser to get 13' + good quality 3.5mm speakers/headphones instead? 3, Screen size: Is 13' good enough size for word processing/browsing? Any experiences of feeling 'I wish I saved up for bigger screen on 15'... I found 11' laptops too small, using 15' laptop which is okay. Conclusion: 13' should serve me good, but will I regret in couple of years' time? 15' should be best of everything, but will I regret spending too much money? I won't know these answers until I can be convinced by existing users, so I really need advice from casual users who only use computer for browsing and word processing, especially if you have been using 2006/7 MacBook models and how they feel using them today.
