It's still very easy to choose computers with modular RAM, even in portable formfactors. The classic SODIMM module format seems to have run its course and is not compatible with modern low-power memory but we now have the CAMM module which at least Dell and Lenovo are shipping and major memory vendors like Crucial offer replacement/upgrade parts for.
Obviously if you prefer your computers fruit-flavored you're SOL, but that's not news to anyone either. Their memory packaging in the M-series machines has its own advantages that may be worth the tradeoff depending on your application, but for a normal user it's more of a limitation than a feature.
As I pointed out in another comment, RAM is soldered on most non-desktop computers these days. It's not easy to expand later. The hardware companies are well aware of that, pushing overpriced RAM upgrades at the time of purchase and it's not like you can just walk into a store and say "I'd like this laptop but with last year's GPU model and 2x the RAM for the same price."
