The Acid3 Test is a standardized rendering test of web browsers (both desk and mobile) in which any score under 100 is considered a “failure.” As you can see from the above screen caps, Safari on the iPhone gets a perfect 100 — while the new Opera Mini browser comes in a distant second with 74.
(To put this in perspective: this writer’s day-job computer, running IE 6.0 — yeah, we’re not exactly cutting edge here — scored a 12. A twelve…)
When we reviewed the Opera Mini browser for iPhone, we totally forgot to run this test. Mea maxima culpa.
