The decision to go with a 64-bit version of Vista over its 32-bit counterpart remains a dubious one, but not so as far as netbook vendors are concerned. Most new laptops are now shipping with a 64-bit OS. Take Best Buy's newest shipment of HP laptops, for example, who shows 11 models listed as "new arrivals." All but three come with Vista 64-bit, with the remaining models sporting Windows Vista Business downgraded to XP Pro, also in 64-bit form.
Falling memory prices could be one reason for the sudden push into 64-bit territory. Of the 9 laptops outfitted with Vista, all of them come spec'd with 4GB of RAM. But is a 64-bit OS truly necessary to take advantage of 4GB or more?
"The 64-bit versions of Windows can utilize more memory than 32-bit versions of Windows," Microsofts writes in its FAQ . "This helps minimize the time spent swapping processes in and out of memory by storing more of those processes in Random access memory (RAM) rather than on the hard disk. This, in turn, can increase overall program performance."
Running 4GB of RAM on a 32-bit OS isn't a complete waste, but because most systems will only show around 3.25GB as being installed, it's easy to see why notebook vendors would opt for a 64-bit OS to avoid customer confusion. Throw into the mix that hardware and peripheral support in Vista 64-bit is very good and it becomes a low risk option.
