Hello everyone, So, after the recent disappointment of WWDC and me needing a new MBP immediately, I jumped and scanned eBay for deals and ended up buying two of them..yes I know I am a pig but I'll sell one and I need your help. Both of them are early 2015 with force touch trackpad. The rest of the details are: I5, 8gb, 256gb, 2(!!) battery cycles, no warranty, mint condition (bought for £727) I7, 16gb, 512gb, 30 battery cycles, 4 months warranty, mint condition (bought for £1,095) And the question is which to keep and which to sell. I know it depends on my use and my needs and here's the thing: I don't care one bit for the I7, the differences are negligible I don't win anything performance-wise, I don't do any video editing etc so I won't notice the difference, BUT I do need as much RAM as possible and the 16gb is good for future proof. I do also like the 512gb SSD but it's not a deal breaker, I could live with 256gb and some SD card/external drive. So, the natural choice would be to keep the I7 but I'm kinda worried about the battery runtime trade-off. Battery runtimes are one of the main elements I opted for a macbook and I don't want to give away too much battery runtime for no performance gains. If the second system would have an I5 it would be awesome. Anyway, what do you think?
