$799 machine. If that.

It's designed that way. Mavericks is intended to use all the memory that's available, so it does use more than other OS versions instead of just letting extra memory just sit there unused. Using memory shouldn't be a problem, only if the machine is running out of memory and doing a lot of swapping.
this is not a new behaviour of OS's though. Most modern OS' do this sort of memory caching. That is why I want to see the actual screenshots instead of jjust people saying "I ONLY HAVE 100mb free!!!!"
I want to see how much is being cached and how much page file people are going into.
One of the greatest issues with this form of caching and the reporting is that it isn't straight forward for the average person to understand. They see that "free" number, and assume, that they've blown through their RAM usage.
hence why i want to confirm when people shout that 4gb isn't enough, or 8gb isn't enough, or 16gb isn't enough.
Realistically, average everyday usage should not be using much more than 2.5-3.5gb of usage. unless you've got a few hundred tabs on a browser open, or using something with a notoriously large memory footprint.
my question for asking is purely empirical knowledge, not to use for judgement for or against. HOwever, I don't understand the logic of going to the extreme micro-soldering laptop ULV parts when space and power constraints aren't as strong. There's a trade off here. You're not getting a better computer. They're opting to go with ULV parts, soldered, non replacable, all in one circuit board where it is completely not required.
