Why do people insist on saying 'X browser is using memory more efficiently' when all they can really conclude is that 'X is using less memory'? If that memory is being used to appropriately cache resources, speed up history navigation, etc., etc. then it's not being wasted. Freeing up memory that you're going to be wanting to re-allocate and re-fill in a couple of minutes is truly wasteful. When you only test how fast a page is ON INITIAL LOAD, you get no idea about how effectively memory is being used.

Joe Public shouldn't need to know about uploading, or hosting plans, or bandwidth caps, or service contracts or the like. Opera open, files open. Opera closed, files gone. Like opening and closing a window.

Yep, I'll bet that a profitable browser company that continues to expand and make more money year after year is definitely in trouble. People have been predicting the death of Opera Software for over a decade now, and yet they're still making huge waves in the internet market. When will people start to realise that you don't need to be the most popular product on the market to be successful? The browser market is absolutely huge, remember. Even 1% of the entire market is millions of satisfied users. The only thing that matters is that open standards are implemented, then we all win.

Probably around the time you realise that object-oriented doesn't mean class-oriented.

Remember, it's a whole ecosystem we're talking about, which includes non-living aspects as well. The destruction of a few species won't destroy the planet, much as heart disease won't kill a human instantly. Removing the heart would be more akin to drying up all the oceans - no water flowing, dehydration for almost all plants and animals, with no means of adapting. It's not the nature of the change, it's the scale, speed and interdependency. Cells don't evolve within the lifetime of the organism, because they are restricted to a single set of DNA. They are still sets of interconnected processing units each handling a specific task with no knowledge of the whole.

It's not about the features that some browsers support now, it's about using those implementations as references to make sure that when other browsers support them, they support them compatibly. You may not notice now, but you will notice in the future.
