Re: Does it matter?
On amd64 architecture 64-bit applications perform better due to doubling the amount of registers. There may be a small hit by the larger pointer type but it's usually negligible.
Also, with 64 bit address space there's more room for ASLR and that's a security benefit.
And if we can get rid of all 32-bit applications on 64-bit windows we can probably kick WOW64 in the gutter. Although I'm sure MS will still use it for obscure reason that is not immediately obvious.
