Apple also have this problem. If you want a laptop with 2TB+ storage you must get it as a BTO option. Or if you want a 14" machine with 32GB RAM. You have to be happy with Apple's random SKU choices that go light on SSD and RAM choices but heavy on CPU performance. Either pay a bunch more to get CPU performance you may not want or need to get the storage and RAM you do need or wait.

At least with a lot of PCs you can upgrade RAM/SSD yourself and get it quick from Amazon rather than wait two weeks for the factory in China to do it for you.
