I'm in the same boat. I just got a A215-S4697 (AMD) and am trying to minimise Vista and remove all possible unecessary junk.
So far I got rid of all the preinstalled games, and the McAfee trial version. I'm guessing you could ditch alot of other stuff too, but I'm not sure where to draw the line.
I want to trim it down as far as possible. [Someone mentioned they thought that Toshiba Flash Cards used a lot of space, and removed it to great advantage.]
Any other suggestions?
