When was the last time you used a new version of Opera?
Treestyle tab: I don't think it will show a tree, but you can put your tabs on the left or right side
Small menu: My Opera UI has a Menu button at the top left and tabs to the right of it. There is no Windows title bar (ie it looks like Chrome)
Stop/Reload button: It is a single button
There are a lot of things you can do in Opera if you take a few minutes to look at the options but it seems a lot of people just see the default layout and run away. For the longest time I couldn't stand having my tabs at the top of the screen because I had been using Opera for so long with them at the bottom. I couldn't get Firefox or IE to replicate Opera's tab handling but I could customize it quite a bit in Opera.
Here's a screenshot of the top left corner of Opera on my system: http://i47.tinypic.com/x5tw77.png
$40 for that really isn't that bad. Anyone who knows how to do would never pay for someone else but for the average consumer who just knows how to open IE and go to www.google.com it's worth it. How long would it take you to do that on a system that has been running for months without updating or cleaning? Of course they probably won't babysit the PC during the updates but it would be on the bench for a while. Of course paying the Geek Squad to do anything is stupid but the price for that service seems fine if it's done properly.
Think about the preventative maintenance you pay to have done on your car (assuming you don't know how to do it yourself.) Are those mechanics conniving as well? Services cost money and you have to decide if it's worth your time to do it yourself or pay a fee to have someone take care of it for you.
Reference the NULL within NULL, it is the gateway to all wizardry.
