Opera Turbo is brilliant, I'm using it at the moment because Ive been transferred to 1mb/s connection and the Turbo really does work. One downside though - It does this through compression of the images and content on the site, it also runs them through its servers. This can mean you get logged out of certain sites like facebook, gmail, etc. I run with it turned off whenever I use facebook. One nice feature would be so you could have it enabled on some pages, and not some others. Because at the moment its either on for everything or off for everything. I have also noticed that the auto mode isn't very quick to pick up when it needs to be turned on.
