I've been using 7 for a while now, and i've had it run smoother than either vista or xp out of the box.
In short, S-99 is talking out of his ass if he believes 7 needs a quad.
I read it as S-99 saying that it's silly to "need" a quad-core for a desktop machine, that it shouldn't be a selling point for quads, and that if Win 7 "needs one" to be "useable", it's an example of MS bloating up operating systems.
That being said, I ran Win 7 on a single core Celeron (Core2 based), and it was perfectly useable for most web-surfing tasks. It even ran Sims 2 fairly well with the built-on Intel graphics chip and 2 gigs of RAM.
the only thing i dont like about 7 is it does not run on decade old hardware. my old amd machine which i built in 2004 ish can run it, but your average dumpster computer does not. i think this is why linux users hate 7 so much.

While I don't "hate" Win 7, I do harbor a strong dislike for it, primarily because it is such a resource hog.
When I can take my old laptop (Pentium M, 2 gigs RAM, GeForceGo 6000 series video) and run an install with Compiz Fusion (read: all the eye candy I want) for the desktop, it's snappy and very useable. Put Win 7 on the same system, and I can watch the thing choke. With this fact alone, I can see where a lot of people get their extreme dislike of Windows.

However, I do have to hand it to Microsoft, Win 7 is what XP really should have been. It's pretty darned stable and does run well... on new enough hardware, which in itself is a good/bad thing.
Vista, OTOH, is the WinME of it's time... Pushed out way too soon in response to a competing operating environment. (ME was in direct response to BE OS, IMO. Vista was the answer to Mac OS 10, which was starting to get some rather big buzz at the time, assuming I recall correctly)
Then again, perhaps I'm just an old fogey and too much of an 'old school' geek. I still remember assembling an PC/XT-class machine out of spare parts...
ISA cards for the real time clock and RLL/MFM Seagate hard drives that used stepper motors and needed to be parked before powering down, DIP memory chips, and 640K maximum memory. CGA graphics was a luxury, and an Adlib sound card, what an amazing (and expensive at the time) thing!

You kids don't know how lucky you have it, now get off my lawn
