well my netbook is ok, but yes a dual core cpu would certainly be nice. the trouble is that i am trying to stay within a budget and keep the laptop lightweight and slim (11-14 inch screen). I wont be using this machine for gaming or anything, the biggest possible program would be solidworks or some form of autocad. I realize those are far more intensive on the graphics card, but again, i dont know of any lightweight slim laptops that have a dedicated graphics card.
EDIT: I also dont care about win7 since i already have a copy of it, so purely from the perspective of the processor, is the solo really worth upgrading to?
