The wand lacks in its ability to poorly manage multiple login names per site, the ability to edit stored passwords so you do not have to DELETE and then RECREATE your login in opera, and various other password field catching code. Yes, it can catch some sites, but sites like bank of america where you get a second prompt requires 2 separate logins for opera. I can do this in one fell swoop in roboform.
Also, the bookmarklet is nice for roboform but it is no roboform toolbar. Yes, it works ok, but it is slow and requires you operate online. In my profession, I use roboform in instances where a connection to the commercial internet is not possible. That is where roboform shines above all others. It allows me to operate in the environment of my choosing, how I want.
But yes, opera does have quite a bit of catch up to do on A LOT of their features. Most of their features are created so that opera can say "We did it first" and then left to stagnate. This has been proven time and time again where a new feature will be introduced and never touched again.
