Opera - Version 4.0 Tired of 10MB+ downloads, megabytes of updates, sluggish performance, HTML standard violations, desktop domination, instability, the seductive word 'free', and a browser war that left you as the only casualty? Then welcome to Opera! Small, fast, customizable, powerful but user-friendly, Opera takes the wait out of the Internet, reduces your online charges and does what the others tried in vain: it puts a big smile on your face. With all these features, Opera is well worth paying for.
