not really sure what this whole discussion is all about but i'd like to throw my to cents into it...
just for the fun of it, i just launched every (to me) important application i currently have installed on my 8gb rMBP and if possible, put some content into them:
*) firefox with 6 tabs and one flv-live stream in 720p
*) vlc plays a sd-quality movie up right
*) adium
*) mail
*) iterm2 with six running ssh-sessions
*) textwrangler with two opened documents
*) ical
*) xcode with having a medium sized project open
*) cyberduck being connected to a server over sftp
*) libreoffice having a single document open
*) aperture showing a high-res picture
*) some openvpn gui with three running tap-sessions
*) ms-rdp client with one open session
*) citrix receiver connected to another server
*) itunes playing a muted playlist
*) steam
*) and last but not least previewing with a pdf-file
and i am still having 2.62 GB of ram available according to istat.
I haven't put adobes cs 5.5 on my machine yet, but I expect that launching ps and / or indesign will lower that just another GB. and no, i didn't forget about virtual machines, but assigning 2gb of ram to a virtual machine is a lot for most things one's gonna be doing in there, too - and bit a paging here in there won't slow down things too much either.
hell, aside from the fact that being human and even male and therefore genetically not even able to handle multitasking and using all of the apps, and not even able watching and listening to all of what's currently playing and going on here, I'm having a hard time getting what 16gb of ram could be useful as of today.
i'm NOT saying that there are NO usecases at all for having a 'workstation' with that amount or even more ram (they do exist) but i'm pretty sure (from my professional experience) that most people won't need 16GB for the next couple of years.
there were times i was havily used and sick of stuff being paged out (ram was expensive and so were fast 15k scsi-drives to compensate on that a tiny bit) but since solid state drives have become available, I see no point in closing applications you're not using it anyways. launch times of anything have gotten so drastically reduced, they can be ignored at all as far as i'm concerned.
on my old mbp libreoffice took almost 25 seconds to open. the ssd reduced that to three to five seconds now.
i have always been someone saying that you can never have enough of ram but when saying that, i almost alyways refer to machines running services like ESXi, terminal / application / database / file servers.
workstations as of today are so ********* fast that the only show stopper around is the person in front of it
i'd rather always recommend going for more local storage space with any highly MOBILE machine so you can leave you big and heavy external harddisks at home while on the move.
just why is everyone worrying about that how much memory is available to ivys integrated graphics chip? it sucks when it comes to graphics intensive stuff NO MATTER how much memory it can access. it doesn't cosume as much power as the dedicated nvidia but if you're going to play games, you'll be having your power supply around anyway.
well, i fully agree to anything what 'themacbookpro' guy is and has been saying and that 'blow45' is just full of it... sry
