Nope, it's definitely not the platform. The hardware cannot cause these kinds of problems with memory usage. That is a fault of the software. In this case Windows Vista.
I am running XP Pro on my desktop and laptop with virtually the same programs being loaded upon boot. The amount of memory and swap file space being used is almost the same with the laptop being slightly lower. So that tells me that it definitely is a huge problem with Vista.
I mean, I have Norton's Antivirus along with the latest Zonealarm installed and running on the laptop and still around 250 meg of swap file used and around 400 meg of ram used and that is with the shared video ram set to 128 meg compared to 1000 meg of ram used and 700 meg swap file on Vista. I mean the differences in the amount of memory being used is phenomenal. Running XP Pro uses half the ram and 1/3 of the swap file space compared to Vista Home Premium.
I even went to the local computer stores and checked the other brand of laptops they had on display with Vista Home Premium running and the results were pretty similar. Almost no free ram and high swap file usage. Some laptops can MASK the Vista bloated slowdown by using high speed 7200rpm hard drives. This does make a big difference in perception of speed when loading applications. And you will not find Vista Home Premium on any laptops with less than 1 meg of ram because it will barely run.

You can find Vista Home Basic on 512 meg laptops but not Premium. That should tell you something right there.
Now I will admit that once an application was loaded things worked well because the swap file wasn't being accessed anymore. But when I tried running multiple applications like my favorite browser and UE Studio things started slowing to a crawl when I had to move between the two application windows. There would always be a nasty delay as memory was moved to the swap file. It was annoyingly unproductive. Having to wait from 1-10 seconds when moving between applications does not make for a productive environment. When I would load up a third or forth application things would get even worse in the delay when switching between apps.
Since I have installed XP Pro I have none of these problems. I can have 4-5 applications running and still have free system ram, far less swap file used and absolutely no delays when switching between application windows.
It's all about how fast can I get work done and Vista Home Premium with 1 gig of ram sacrifices productivity for being pretty and having an ineffective but more intrusive security package. I am sure that I could have cured the problem by adding another gig of ram to the laptop but that is still only MASKING the problem.
And the reason I posted the above information about the driver download is because I have had 2 emails from F572US owners who read my blog and wanted to know what drivers were needed so they could switch from Vista back to XP.
