I've kind of been out of the loop on mobile chips lately, but have been looking at buying a new laptop... are the "APU's" the chips that contain both a process and a GPU?  And they are good?  I'm looking in the $600 or less range, but can only find integrated graphics on the Intel side with those, and decent dedicated GPUs on the AMD side.  So I like the looks of the AMD offerings on paper, but I am just concerned about the CPUs themselves - power usage, actual processing power compared to the i3/i5's, etc.  And what's the difference between A6/A8/A10?
