I wonder how they did with Android? Especially in the early days, not with today's 8GB+ monstrosities.

My first Android device was a Nexus One. 512MB of RAM for what is essentially a full Linux system. Able to run a browser and multiple Java apps, all isolated and running their own VM. Task managers often reported near 100% RAM use and things still worked fine.

And my understanding is that optimized things further, but given how overpowered phones are today and how bloated apps are, it is hard to tell.
