I know 32 bit operating systems in the past wouldn't read more than 3-3.5gb of memory, but I don't know if that is inherent to the 32 bit OS, or if it was just for the older systems. I am curious to know if W7 will read more than 3gb of memory.
Surely the best "wonder feature" would be to allow W7 to use more RAM! I believe all 32bit versions are crippled to make the 64bit versions seem more attractive.
If W7 could utilise 8Gb RAM I would buy it straight away!!! Otherwise, stick to XP...!
