This reminds me of how movie theatres offer a small, medium and large but the large popcorn only costs slightly more than the medium, thus enticing you to go for the large.
Only recently Lenovo started to solder their parts so base models lost their power :(
The spot price for 16GB of LPDDR4 looks like it's currently ~$8 per DRAMexchange: https://www.dramexchange.com/
They're also charging $200 for a 256GB storage upgrade - spot price of 3D TLC is $3/256Gb ($24 for 256GB) - you can currently buy a 256GB NVMe SSD (full stick with controller) at retail for <$30 as well.
Many laptops now have soldered RAM, but other vendors have not chosen to do what Apple has done. In HP's premium laptop (Spectre x360 13t), adding 8GB of RAM is a +$70 option. For reference, an 8GB DDR4 SODIMM at retail pricing is about $30.
Also, AFAIK, no other major laptop or mini-desktop manufacturer uses soldered storage like Apple does, so in this case, the retail cost for storage is even more relevant.
These are commodity parts, so there's not any R&D to recoup - this is just profiteering on Apple's part. Especially for the Mac Mini, where there's not the same space constraints, the lack of storage upgradability is also a rather egregious form of forced obsolescence. Fine from a business perspective, but hypocritical for a company that claims to care about the environment.
You can call me bitter but this sort of manipulation is making me extremely salty to the point where I'll be having seething hate for the company for the rest of my life.
