The preview on tabs can be made visible without the need to hover over them, simply by extending the vertical size of the tab bar. (Or horizontal size, since it's possible to have a vertical tab bar on the left/right in opera).

Admittedly Opera's torrent client is pretty limited and weak in comparison to a full client, but it's certainly useful for non-techies who don't have a clue what a torrent is when they just wanna download something.

You can sync opera notes along with all your other stuff. (Incidentally, Opera was the first browser to include sync.)

Opera aint limited to mouse gestures, but also has voice gestures, if you're into that kind of thing, although I'm with you and rarely use them.

Clone tab doesn't merely copy the current location of a tab, but copies over the whole history of the tab too, which is often useful if you wanna navigate back but without losing what you're currently doing.

I think there's more unique features of Opera than the ones he describes here. In particular I like the fact that Opera contains a full stacking/tiling/tabbing window manager, and you're not limited to "tabs which consume all the space". Nice to browse two webpages beside each other. (The tiling features could do with some polishing, but they're non-existent in other browsers.)

I was a long time user of the software, but I primarily use Firefox now, due to a growing number of problems I had with Opera and the lack of customization you can do with it (since after all, it's not open source, and configuration is done with crappy text files). It's worth a try though, Opera have continuously pioneered many of the features in all the browsers we use today.

> Mouse gestures: > Firefox has that (with an extension), I tried it but never liked it. I tend to play with my mouse all the time, and triggered gestures by mistake

Opera's built-in mouse gestures are infinitely superior to the FF extension, and are actually very useful. Tabs and mouse gestures were the reasons I went with Opera a long time ago. They also had some useful keyboard shortcuts that were pretty handy ('z' to go back in history, 'x' to go forward, etc) which made it perfect for quick surfing since my right hand manipulated the mouse, while my left hand was naturally positioned over these keys.

Unfortunately, there came a time when Opera suffered some intermittent and annoying crashes. I switched to FF, but it was much slower and the gestures were horrible. Finally, when Chrome came into the scene, I switched to it and never looked back.

Also, since my switch to a Macbook Pro, I can use the double-finger swipes for backward/forward navigation, which are really the only useful gestures for me.

It's only faster to click the tab once. The Web Page preview appears instantly after the first one when hovering over the other tabs. You can't click all tabs faster than you can hover over them.

I have my notes, bookmarks, speed dial and saved passwords synced everywhere, as I use Opera everywhere.

You can't clone tabs with all history manually in 1 second. The history part is what makes the feature really useful.

In Chrome, you can clone a tab by command-clicking the reload button.

In Firefox by holding control and moving the tab.

Or Middle clicking the refresh button.

Or right-click the tab->Duplicate Tag, or Ctrl+Alt+T.

And my axe.

The preview tab feature is standard in SeaMonkey. But I guess no one - except me - uses SeaMonkey (it also has built-in Mail).
