Coast by Opera has been out for 2 weeks now. During that time, we’ve been browsing a lot on our iPads and we’ve noticed that there are still relatively few sites that are really optimized for tablet browsing: Coast by Opera gives you a good experience on non-optimized sites as well, but still, things can always be better.

Opera 14 Beta for Android Is Out

by Andreas Bovens in Blog

Yes, that’s right: 14.
