I think everyone is looking at the transition the wrong way. What happened is that the original Opera browser that we all loved has simply been discontinued. The company that used to make it is now making a different browser for a different market and, unfortunately for old users, is using the same brand name ("Opera") for it. Thus, we download what we think is our Opera and instead get something else.
I was shocked and confused like everyone else. I am a huge fan of original Opera, and it took me a while to figure out that what now gets downloaded under that name is not the same program. I kept looking for the switches to turn on the features of the other product!
I have no use for the new product, so I'm grateful to have found in this forum how to get the old one (to install on a new computer), and when that stops working, I'll probably fall back to Firefox - it seems to be the closest alternative to original Opera.
But developers of the new Opera aren't stupid. They didn't intend for it to please people like me. They've figured out that people like me don't pay the bills for developing that incredible browser. It's a pity, too, because I would personally pay $100 a year for it; I guess there aren't enough other people who like it that much.
