Hi guys. I already searched a lot about this situation, but I need some advice, because time is running short and I need to make a decision on what MBP 13" to buy. I'm a college student and I will start my Master's Degree in September, I study Psychology. Some of you may think that it may be a waste of time to just buy a MBP, but I really need a fast computer that can handle the type of work I do, which is basically word processing & presentations (90% of the time I need to have multiple documents open), large & heavy pdf's (opened at the same time), web browsing, sometimes photoshop and video editing. I live in Portugal, so prices here are a little different. These prices are with student discount applied. For the MacBook Pro i5/4GB RAM/500GB disk, they are asking for 1220, which equals to 1500 USD and for the MacBook Pro i7/8GB RAM/750GB disk they are asking 1500, which equals to 1850 USD. I want my MBP to last for a good couple of years, maybe 4 or 5 years, at least to the point where I feel the need to change computer. I went to Premium Reseller here in Portugal and the employee advised me to get the i7, which was on my limit price range. But he also told me that I would be fine with the i5 version, which was more than enough for what I'm doing/will do with the MBP. He also advised me that I could get a MBA, but I don't like this model and I prefer the MBP. I'm afraid that I will get tired of the i5 version in a couple of years. If there is one thing that I absolutely deslike is to work on a machine that responds slow, which can be frustrating and a waste of time. On the other hand, I don't want to spend money that is not worth for the type of work I will do. I tend to have a lot of applications opened at the same time (I need them) and I'm afraid the i5 may became slow with the development of new software versions. But I don't know if the i7 is really that necessary. I don't know if I made myself clear, I hope so. Thanks in advance.
