first point IS valid, integrated graphics solutions, regardless of the manufacturer, needs to take memory from system memory, but that memory is actually reserved (in a dynamic way, but still... reserved), not 'shared', a quick example could the Intel GMA 4500MHD in my previous computer (an HP Compaq CQ-60 laptop), which could use up to 17xxMB of system ram, my available memory was something like 2.45GB~2.95GB under Windows 7 x86.
(and I guess the same applies for NVIDIA and ATI with their 'shared' memory approach).
