Its funny, I hang out in some Mac forums and have yet to hear anyone say they went back to Tiger from Leopard
I never said anything about going back to Tiger. Only that I have read posts by many people saying that Leopard is buggy. I do agree, I come across some bugs daily in Leopard. It's not a big deal really, I still like it.
You can find most of these comments on appleinsider and macrumors in the sections about the announcement of snow leopard.
You can dance around the issue of how Vista uses its RAM all you like, the fact is I have seen many Vista machines that are running 3-4 gigs of RAM and are still slow.
Drivers. It keeps coming back to that. You haven't mentioned the specs on these systems either. However I provide benchmarks below showing what superfetch really does.
It happens. I have actually been kicked off of other forums for not liking Vista. I guess every OS needs its fanboys, but to make such obviously wrong statements is beyond me.
Because there are benchmarks to back it up. And many user accounts. You see what you choose to see. Like I said, with good drivers it is certainly as fast as XP if not faster and is more stable. I'm not saying XP is not stable but on my system Vista x64 does not crash, does not lock up and does not BSOD. I have 3 weeks uptime before a power surge forced a reboot. I have not been able to achieve that on Leopard. But it's not a big deal for me.
I have Vista on 2 machines here and can verify this. I have talked with many others who also agree.
It's all about your drivers and your hardware. Drivers which improve all the time so it would need to be tested with each new release. And with the right setup it is rock solid. I also have yet to run into any compatibility issues. I have a Vista HTPC setup to play every video format under the sun, all from within Media Center.
You have to be able to differentiate between OS issues and driver issues.
I'm not sure how I could be a fanboy when i'm writing this in Leopard. I like Leopard, alot. I spend more time in these days than I do in Vista.
Some people simply hate anything Microsoft just because it's Microsoft and see only what they wish.
Here are just some gaming benchmarks showing Vista vs XP. It edges out XP here by a hair. It's also almost 2 months old so there has been several driver updates since then and I imagine performance now would be even better.

Final Thoughts:
If you were expecting a huge drop in performance as your eyes scanned from the XP to the Vista results, well, surprise! As many a tech analyst predicted, Windows Vista's gaming performance conundrum has largely been solved, and it was mainly due to early graphics drivers.
In fact, I'd been planning to run a few other gaming tests, but the results from these were so uninteresting that further work didn't seem merited. Love it or hate it, Vista is performing far better than it used to.
Game performance, it seems, has been exorcised from your concern when choosing a Microsoft operating system. That leaves a few other factors, of course: stability, responsiveness, eye candy, price, DirectX version, and a few other odds and ends.
It took about a year and a half, but the performance gap between Vista and its forerunner has finally evaporated.
Here's another review. This one is 9.5 months old and obviously drivers have matured since then. And issues were addressed in regards to SLI. In some cases Vista is faster, XP in others but in most they are neck and neck.

Here's some more from January, Even shows some superfetch benchmarks which you seem to think doesn't work.

It's interesting to see that Vista's performance seems to have progressed since it was released.
The general usage tests are either faster or equal to XP. It should be noted that the program load times may be influenced slightly by the fact that the OSs reside on different drives (Samsung/WD). However, Vista is on the slower drive (the WD), so it only makes the results even more impressive. Talking about the program load times,
it's obvious that Vista's SuperFetch feature works wonderfully. Even though I've only launched Photoshop and OpenOffice a few times, Vista has already picked this up and loads them into mem right after boot up.
Crysis was almost certainly not cached into RAM during the test, but still loaded faster than in XP.
The horrendous file copy performance has been fixed.
Performance is definitely higher than in XP. Also gone are the sometimes irritatingly long file deletion times. File deletion seems instantaneous now, just like it's always been in XP.
This is a very old article and performance has changed a great deal since then, but this page on superfetch is a good read:

And here is a new link on hardforum to what other users are saying:

I believe you said XP is 20-40% faster? Maybe you've decided that Microsoft is evil and therefore you can only believe bad things about all that they do? I don't know when you've last tested it, I don't know what patches it had or what the hardware specs were or what driver versions you've used. If you are just setting it up for someone and leaving you wouldn't see that in time superfetch does make it faster as seen by the benchmarks above.
I think it's clear in benchmarks that it all depends on your hardware and drivers. Some show Vista slower, some show it faster. How can the same OS give different results? Again, drivers. One person benchmarks it with poor drivers and you get bad results. You benchmark it with better supported hardware and good drivers and you get better results.
Sure the home user isn't going to care about drivers, they just want it to work. And any problems as a result of drivers is seen by them to be an OS issue.
Luckily Windows 7 uses the same driver model and hardware vendors would have had more than enough time to get it together.
Now i'll tell you what my problem is with Vista. All the different versions of it is just plain stupid. And it's organization is a clusterfuck. I feel like I have to look all over the place for a setting that should all be contained a streamlined in a single location. By comparison Leopard is highly organized and very clean. Does not feel cluttered like Vista at all.
Despite whether or not we like or hate Microsoft, Apple or Linux it's important to stay up to date with the latest info and not to let any personal bias we feel get in the way of that. Of course finding the time to sort through vast amounts of info isn't always so easy.
