Usin Readability, users with any browser can head to the bookmarklet's setup page, choose a few reading options, then drag a "Readable" link onto their bookmarks/links toolbar. The major difference with Readability, other than the voluminous font, size, and layout options, is that a readable text scroll appears as an overlay that greys out the rest of the page. It can auto-grab the main reading text off a page, or you can select the text you want to read and hit the bookmarklet.
Here's a clip of Readable in action:
