Here are the stats for all three operating systems (XP, Vista and Win7), with memory usage measured after all update operations had completed and the system had been idle for at least one hour:

Windows 7 uses less RAM and disk space than Vista

As you can see, on this low-resource configuration Windows 7 uses dramatically less RAM than Vista, and also has a smaller hard-disk footprint.

No, Windows 7 has the same requirements as Windows Vista, but performs better on the same hardware, utilizing the hardware better.

nah, it utilizes the hardware pretty much the same way as vista. What Windows 7 does is to cut down on the bloat and focus on end-user experience (thus superbar, plus reduced mem and disk usage).

It's a slimmer OS, I guess.

Isn't reducing mem and disk usage better utilization of the hardware?

Isn't software made to run/(run on) a hardware? Isn't software altered according to hardware(we're talking about code here)? :) Obviously, code is altered in order to interact in a better way with the hardware.
Still, we can agree to disagree, if you wish. :D

Yeah PRATOSH i agree that with (nearly) same requirements obviously Windows 7 beta (latest build?) still outperforms Vista (SP1?) in this case. That's the point i like about it since i have the same experience. And i'm sure even the next version or RTM will do much better than it :D Amen! Seven Rocks!

OMG NO WAY!! Let's compare 98SE and 2000. I bet 2000 will beat them both! We should all switch to Win2000 since it uses less resources.

I bet Win 2000 couldn't support our hardware :P

And yes, I do know its sarcasm. But it was really pointless.

I use XP Pro on one drive with Office XP and Vista with Office 2007 on the other so I dont need 7 to get speed or compatability as XP performs around the same.
