Within the last few weeks my MBP went wrong for the first time, after a few visits to Apple they replaces the logic board on the unit covered under consumer law which would have been circa £500! Now I've noticed the keyboard illumination has gone so they are now replacing the top case assembly and batters at a further cost of circa £400, again covered under consumer law... So I almost now have a brand new machine which is a high spec i7, 500gb SSD and 16gb ram so is still performing very well. I have multiple USB3 external drives and use my SD card slot a lot from my Fuji cameras, GoPro and DJI Drone. So if I upgrade I have a big initial expense plus all the dongles I need to get my SD card and USB3 drives going on it... Would you do the same?
