Android/Windows Mobile/BlackBerry: Opera's Mini browser isn't the same as its Turbo-sporting Mobile, but it's still got a neat start page, smart image controls, desktop syncing and fast rendering. All of that has just landed in the Android Market.
Why consider Opera over the built-in, WebKit-based Android browser? For one thing, if you're using Opera on the desktop, you can enable Opera Link support to sync up your bookmarks and start-up page links. If you find yourself more often than not on a slow connection, you'll also like Mini's ability to set lower image quality and thereby speed up page loading, restoring the images once you click them.
There are smart download and password managers, too, but the other killer feature Opera Mini sports is a kind of tabbed browsing. Hit the tabs button while you're on a page, and a spread of tabs and a new tab button line up on the bottom, like a hand full of cards. It's a good interface for flipping back and forth between sites, if that's the kind of thing you do while on the go.
Opera Mini 5 Beta is a free download for Android phones, available in the Market or by heading to opera.com/mini/next from your mobile browser. It's also available for Windows Mobile and BlackBerry models at the same page. If you're considering making it your default Android browser, or holding out until Mobile arrives, tell us why in the comments.
