I gave it a run while I was at my mother in laws (I don't know if they even support linux) and I really didn't see anything stand out. I used to be so about opera and then they fucked it up. I went to FF3 and tried new opera releases here and there and they just never got back on track. With this latest one it feels like they are *starting* to catch up, but are just surfing the wake so to speak.
But that's just my feelings on it, others may love it and I only played with it for an hour or so.
