RAM helps multitasking, it doesn't help boot or apps opening time all that much. I usually run Opera with arround 12/15 tabs, Firefox with 8/10 Chromium with 5/8, 2 LibreOffice instances, Banshee, Pidgin, Meld, Gedit, Geany, Transmission, Thunderbird, XChat and 7 workspaces. With all that I have almost never seen my memory rise above the 2.4 GIB bar, at least not when I'm not using a VM. So, no, more RAM wouldn't help unless you are doing ***severe*** multitasking or playing with VMs. It will not help boot speed, or the speed in which apps open; it may speed up general system speed, but only when under heavy loads. It is not worth the price; you already have 4GBs of RAM and that is more than enough for the tasks you describe, it is a very decent quantity of RAM, don't worry about putting more

So (theoretically) if you open a bunch of items and close them, they will open quicker the next time - saving disk reads / writes. I have 8 GB of RAM in a system that, at idle, displays RAM usage via System Monitor at 300-500 MB. When I run Top, it will often show the 'used' amount to be significantly higher than the SM display. it also shows the amount cached and after a few days to week of uptime, it's utilizing all of this extra as cache. Of course, this cached mem is released as soon as the system needs it.
The beauty of the Linux system is that it gracefully puts to use as much RAM as you feed it. My web server certainly doesn't need 32 GB of RAM but it sure does love being able to cache all of that frequently accessed data without having to read a disk.
I'd say more is always better and 4GB sticks are pretty darn cheap these days.
Just my .02 and I'm probably wrong but it works for me.
