One of the Google threads that brought someone here was “Opera sucks”. To which I can only say, no it bloody doesn’t (RR, passim).
Opera is an excellent browser, if a little quirky. I originally rejected it because of this, but eventually went back to it – because support for Firefox 2 ends in December – and have been happily using it for over a month, now.
It does, admittedly, have a couple of glitches, but they are probably worse for me and other WordPress bloggers than for the average user (it isn’t supported by Google Gears, its spell-checker is crappy, and saving and publishing new posts is slow, without Google Gears). The spell-checker I can get around by writing in Word and pasting the finished article into WP.
The standard black colour scheme is atrocious for anyone over 12 who isn’t a Goth, but a standard Windows colour scheme is supplied.
It has an excellent Bookmarks search facility, and organising Bookmarks is a doddle – try that in FF3, Chrome, or ‘kin Safari, and see how far you get! And in IE, that function has always sucked, and still does – no search facility, either.
My advice is to just use the bloody thing. Stick with it for a month, then tell me it sucks. If you still think it does then you’re stuffed – nothing else out there comes close to Opera’s functionality.
