You're forgetting the context, being the selection of a device to run Linux (or anything else) on. Also, more memory is more memory, no qualification needed. It doesn't matter why the device has more memory, just as long as it does.

Yeah and it needs "more memory" because it runs Java. Modern iPhones have way more than enough memory to run one app at a time and a few in the background.

Who cares why the device 'needs more memory' (which it doesn't by the way, the excessive amounts of memory in recent Android devices is more of a marketing ploy than a necessity) when the goal is to select a device to run an alternative operating system on? That is, after all, the context of my reply.

Is is, just add `termux` and install whatever packages you want. That won't help those who want to install Sailfish or Ubuntu or their very own mobile Linux creation or whatever other option they might contemplate. For those applications it makes sense to get a device which is open to this type of tinkering.
