I’ve had Opera on my computer for a while, but I don’t use it very often. Today I was reminded of why it’s so nice to have around: it’s the only one of the Big Four (big four IE alternatives, that is) to include a page zoom feature, and it can deliver a pretty good approximation of what your site looks like in a text-only browser (see below). Other style options include an accessibility layout, which is aimed at the visually-impaired and people with reading disabilities.

With Opera 8.0 (in beta, rumor has it it will be ready soon) you also get voice, which is very nice for testing accessibility.
