That’s not what I’m talking about. A simple RAM upgrade really doesn’t count as a modification. It’s only a modification now because Apple’s soldering it to the board now. But RAM is RAM, no matter where it comes from; it’ll work just fine. A RAM upgrade from another vendor won’t wreck your Mac or void its warranty.
The other thing is, what if you get a Mac with the standard 8 gigabytes of RAM and a year or two down the road, you start needing more RAM? Then you have to buy a whole new Mac instead of just being able to upgrade the RAM for $80. Would you rather spend $1,200 or more on a new Mac or just $100 on a RAM upgrade?
Soldering in the RAM makes it so you can’t make your Mac last longer by upgrading the RAM, which forces you to buy a new Mac. So, instead of getting 10 years out of a Mac, you’ll get 2-5 years. That kind of defeats one of the biggest reasons for buying a Mac: Longevity. At that rate, you might as well just build a Hackintosh, but then you have to do a lot of hacks and you have to make sure not to get any OS updates before checking
