I was wondering why my nexus 10 only shows around 1.6 gigs of ram this shows with the widget I use and also under setting>apps>running the total is again around 1.6 gig. Is some of the ram reserved for the JVM or similar?
Pre-4.2.2, out of the 2GB, 400MB was reserved for the GPU. 4.2.2 gives an additional 380 or so MB to the GPU (totaling close to 800MB reserved for the GPU) in order to prevent userspace RAM fragmentation.

Well, **** I think that they should have let it take away RAM from the user, I keep like 15 tabs open at all times and only having 1.2gigs free causes the browser to run out of memory and crash.

15 tabs open is considered excessive on a laptop and low end desktops. Let alone a tablet. As is the case though when it was allowed to rob from the userspace RAM is it was fragmenting it.. Which in a lot of cases probably left you with less usable RAM then you get now.
Fragmented RAM = There is free RAM but because it isnt a contiguous block the OS can't use it. It's sits there completely wasted until x-y-z happens.
Two great pictures showing what fragmented memory is and why it's a problem. These are about Netware servers but the same principles apply.. Fragmentation = Bad and a waste of space.
External Fragmentation
Internal Fragmentation
I usually keep at least 25 tabs open in my first gen i5 laptop without problems (I have 6gbs of RAM though).
And damn that sucks, but would the the unusable RAM ever reach 400mbs?
