Android only: Alternative browser Opera already has a "Mini" release for Android, but by putting Mobile in the Market, they've added their server-side Turbo caching for noticeable speed, a better press-and-hold interface, password storage, Opera desktop bookmark syncing and other handy features.
There's also built-in geolocation support, SVG image rendering, and a few other goodies here and there, like visual tabs. What really sets Mobile apart from Mini, though, is the Turbo caching. Loading up a few of our sites, and a few token Android blogs, I noticed a good bit of improvement over the standard Android browser. Some of the larger images end up a bit more jaggy and pixelated when you first zoom in, but given that much of the mobile browsing experience on non-mobile-formatted pages involves simply finding the one link you're looking for, it's handy to have the full page up and ready for your eyes as soon as possible. Opera Mini, without Opera Mobile's Turbo caching, generally beats stock browsers on page loads, so you can likely expect the same kind of speed-ups here — and more easily set Opera Mobile as a default browser on Android.
Opera Mobile is a free beta download for Android phones only. You can grab it using the QR code at left, or search out Opera Mobile in the Market.
