Exactly. If the browser can handle that many tabs without performance degradation and over consumption of memory, why bother having to micro manage your tab usage every time you open another? Back when I used Mozilla/Sea Monkey (before Firefox) I used to have to worry about all that and it might seem crazy for anyone who doesn't use opera to have that many tabs open. However, most opera users I know (yes, there's shockingly more than 3 of them in the world) use quite a few more tabs than any other browser on average. If I were using chrome/firefox (which I do when I test and develop since I prefer their tools for those things over dragonfly in opera), I would never open that many tabs (though obviously I cant since they consume way more memory :) ).
