For some reason the vibrant one posted above wouldn't 'register' when I put it in my ~/Library/Colorsync/Profiles directory and wouldn't show up in System Preferences. However, you can get it to work if you do it via the ColorSync Utility. Select Devices, then the current display, then under current profile you can browse and select it.

Comparing the Vibrant one with mine via ColorSync Utility they seem pretty similar, but I'm sure my colours are way off.
Hey ism, sorry for the slow response, most of the time I browse I'm at work and I forgot my MacNN login.

I grabbed the Vibrant one from /Library/ColorSync/Profiles...the Library on the HD, not in my user folder. Maybe that is why it wouldn't work earlier? Just a guess.

Anyway, I tried your Si one, it seemed to be leaning towards a pink hue. But I followed those links you posted and tried that one guy's "12 inch PowerBook" profile and DANG--that is a nice profile. Mine is washed out and leans more towards the blue, but his was really spot on with only a TOUCH too much contrast. But I've been using it for the past few days and will stick with it. It'd be cool if someone had a hardware calibrator and could post their profile, that way we'd get truly accurate colors. But I really like that one profile, the colors are very rich and seem to be pretty accurate to my eye. It seems like a very balanced profile and lights years better than the one the PB starts with.

Displays are not consistent enough for this to really work. There are a lot of variables involved that cause displays to need to be recalibrated on a regular basis. It's not a "set and forget" process.

Exactly...

The ambient light in the room has a large effect (office florescent bulbs, vs. natural light, vs. incadescent and so forth), for example.

Got my Rev D 12" Powerbook last week. Everything seems to be perfect except that the screen appears to be "dirty." I mean there seems to be a layer of unkown material trapped inside the screen. Don't know how to describe it but It's just like viewing with a depth of 16bit color on other LCDs...weird.

Yeah, but it'd be good enough for us plebs.

I just got back from the local Apple store. My 3 day old 15" PB died today. I believe it was a hard drive failure. Anyways, while I was there I poked around on a new 12" PB. To my eyes the screen looked quite nice. Not nearly as washed out as my Rev. C 12" did. Compared to the 15" PB next to it the 12" PB looked very good. The screen was not as bright but the colors weren't washed out like my old PB was. I guess it's luck of the draw.

Yes, but there is standard lighting. Also, LCD displays change much slower than CRT displays and don't need to be recalibrated as often.
