A recent article here elaborated on this: http://www.extremetech.com/computing/134760-pc-obsolescence-... (http://news.ycombinator.com/item?id=4412905)

I have 16GB in my laptop (Lenovo T430s). The chipset can support 32GB.

Is the RAM user upgradable? Otherwise it's an unconscionable $250 to go from 4GB to 8GB and no option to go higher.

I would have a hard time going backwards from 16 on my workstation :|

Sometimes heap dumps can exceed 8GB.
