It depends upon the type of operating system and if the laptop can support the amount of memory. Most versions of Windows are 32BIT. This simply means they can "see" a maximum of 4GB of memory. 64BIT versions of Windows can see past that 4GB limitation. Most computers will only see 3.5GB out of 4 (even if 4 is installed) SO, 3GB is very close to the maximum amount that most computers can see. It is also very close to what most versions of Windows will see. Therefore, 3GB is probably GREAT for a laptop.

If I recall, XP can utilize a maximum of 2Gigs of RAM. I do not think there is any limit to the disk space.
