2, the impact is not big, the size of the memory has the biggest impact on vista
3, don't look at the upgrade space when you buy a laptop, there is no sense!
4, I personally think the second one is more suitable for you
Because you don't play large games, so the independent graphics card is meaningless to you; remind you is that when you buy a computer, make sure you don't install the vista system, and let the manufacturer change the XP for you because vista can't be used for anything, and there are not a few software that support vista. My classmates have bought it, they suffered a loss, and finally went to change the system again (because the manufacturer doesn't give the driver disk for installing vista, they can only find the manufacturer to install the XP system)
That sentence is very unintelligible, you can ask the manufacturer what does it mean, it is impossible that 1G of RAM doesn't support 32-bit, but the sentence should be left alone, because your CPU is 64-bit
