Nice.
Just a few remarks:
- Presto was another engine, and is not shown.
- Opera used to be based on Presto, and it now based on Chromium.

@Steve12L
And Presto was damn good.
- very fast.
- it was also the first engine to pass the ACID3 css test with success.
- and Opera was the first browser with TABS.
- Opera application even had a mail, newsgroups and RSS client included in the browser.

How times have changed. 🙁
