Until fairly recently, the MacBook Air came with 2 GB of RAM standard and no way to upgrade; now it's 4 GB standard and still no way to upgrade.
But then I see people typically using 6 and 10 GBof RAM....am I correct that this is not that much of an issue with the MacBook Air because of the Solid State Drive which makes swapping memory between RAM and drive quick and therefore less of an issue?
An efficient OS will use as much as it can. It's not to say 4GB isn't enough. But someone with 8GB is going to see performance benefits (hence why they see 6Gb in use with nothing running; it gets released as needed.)
My machine has 4 GB (max is supports officially) and iTunes just keeps grabbing more and more, particularly when trying to update iTunes Match (which makes it crash occasionally). I'm used to seeing iTunes using upwards of 1 GB, but now it's grabbing as much as 2.5 GB. Maybe it's just iTunes. Hopefully an update will fix it.

Does it spike when you sync your iPhone/iPad? I know both on Lion and ML I have to restart iTunes often because of this.
Oddly since getting ML I've noticed I've had more memory free than normal, but I am also noticing individual processes are using more memory.
Well, maybe Apple shouldn't be selling a 2GB non-upgradable computer at all if that amount of RAM is marginal with the latest version of their OS.
But I'm thinking more of MacBook Airs bought in 2010 with 2GB and no way to upgrade the RAM, even today one can buy a 2GB MacBook Air in the Apple refurb shop.
Those 2010 machines all had 4gb upgrades available CTO
