>у меня и так десктоп+нетбук - «нахрена козе баян»?
На огромном количестве сайтов размер шрифта указан в px вместо pt. Минимальный ращмер шрифта в современном интернете необходим, если разрешение отличается от «задуманного верстальщиками 1024x768».
The sad truth is that designers never really understood the difference between pt and px. Many Web sites even today mix those units in the same Web page. Not only do they assume that pt and px are close to one another in size, they actually mingle these units assuming that the ratio between these two units will be constant across all browsers and devices. Any browser that truly attempted to treat pt as 1/72nd of a physical inch would just end up mis-rendering Web sites.
This is why browsers use the 96 dpi rule when deciding how all of the absolute units relate to the CSS pixel. When evaluating the size of absolute units like pt browsers simply assume that the device is running at 96 CSS pixels per inch. This means that a pt ends up being 1.33 CSS pixels, since 96/72 = 1.33. You can’t actually use the physical DPI of the device because it could make the Web site look horribly wrong.
