Ease of being able to replace the battery has never been the reason stopping me from upgrading from a 2015 MacBook Pro. Anyone with the the intent of replacing a battery today will be able to make it after buying some readily available tools. What I need is the ability to swap out my SSD in the laptop, either for data retrieval, backing up, or upgrades. Unfortunately good removeable storage seems to be a thing of the past. I say "good" because I don't want to boot the newest MBP off a slow SD card. I could depend on Migration Assistant or Time Machine, but I don't trust anything other than a good raw "cat" or "dd" of a drive
