easy, the sz series is slim and light lappy (with camera built in) while the c series is a lil bit bulky(i mean here is , thick), though both built tough. no worry. all vaio lappy built (casing) made with either carbon fiber or magnesium alloy material.

the theory is easy, the more slim, light lappy with decent performance in term of battery supply, or working with office stuff, the price can be incredibly expensive, even with only integrated gfx.
thats it.

Actually both model is more or less the same...just difference in few specs such as weight, build in microphone n webcam, bigger harddisk size.  If u travel often, it good that u take SZ series cause it's only 1.85kg compare to C series 2.3kg.

if you "misuse" it, it's out of limited warranty.
you own vaio dude? try read back of warranty card.

try for C15
its same spec  , only no vista
