Having taken advantage of Opera’s offer (still valid for a few hours!) I must say, I’m impressed. Opera is snappy in a way that Safari (with all the plugins I’ve added) is not. There’s some small bits of things not working as I expect, things that should be controlled differently*, as I move, but there are two big issues that are causing me to consider not moving.
The second is Mac Keychain integration. The Mac has a very nice system for storing and managing passwords, encrypted with your login password, or other password. Opera doesn’t seem to support this. I have literally hundreds of passwords stored in Keychain, and getting them all out and into Opera will be a pain.
It remains to be seen if Opera’s speed is enough to overcome these two hurdles. If anyone has suggestions for either, I’d love to hear them.
[* things that should be controlled differently: One example is skin management: Selecting a radio button for "download new skins" is clear enough, but going and getting new skins should be a different control.]
