Hi, I really need some buying advice for a 2018 15" MacBook Pro. I am going to be replacing an older 15" MacBook Pro and I have all the specs picked out except for the processor: i7 or i9. I am looking to purchase the one that will give my computer the most longevity and not need replacing for a while. This will be my sole computer and my average uses are school work, basic photo and video editing, lots of web-browsing and email, streaming of movies/TV/music, reading ebooks, etc. I am definitely not a "pro" user. So, I think the i7 would suit my daily use, but I do not want it to become obsolete or outdated sooner that the i9 will. I would rather pay a little more now and have it last longer. However, I also do not want the one that will have the most problems. I am not very tech or computer-savvy and just need some of this community's knowledge and expert advice since I am going out-of-my mind with research! Thank you in advance for your help!
