This is the calibration file that I use. i found it easier to read after I changed the calibration settings. Found it on another thread here on macumors:

Copy it to Library\ColorSync\Profiles
After the file is copied, press alt + F2
Go to the color tab
Select the profile to apply settings. (this profile is also called color lcd)
You can tell that you are choosing the right one by hovering over it - It will display the file name CustomMacRumors.icc)
The profile is known to kill darker colors notably blacks but I find it is alot easier to read with this profile.
You can set the zoom level in safari for all pages with an extension called "AllPagesZoom."

I've been using my new Macbook Air for two days now. I've kind of got more used to the text.
Does that profile increase the sharpness of text as well? Also, will that file overwrite the default profile since the default calibration is called Colour LCD as well? Thanks.
