 It's Thursday, November 29th, 2012. I'm Russell Brandom, and this is 90 Seconds on the Verge. iTunes 11 is finally available to download. It's possibly the biggest UI overhaul iTunes has ever seen, with new sliding menu panes and a heavy influence on album artwork. There's also new integration with iCloud, which emphasizes streaming any purchased content, like songs you bought years ago and have long since deleted. The long and the short, it's a big improvement, and if you have iTunes already, there's no reason to avoid updating. Microsoft's Surface Pro now has a price and a release window. The click clack covered tablet is due out January and will start at $899. It's a little heavier and thicker than the just released Surface RT, but otherwise looks the same. Unlike that model, however, the Surface Pro has full Windows 8 and will run all your desktop apps. The other tradeoff is battery life. Microsoft says to expect the Pro model to last just half as long as the ARM-based RT model. Finally, remember when NASA said this week's Mars rover announcement would be one for the history books? Well, the agency today announced that it will not have any major new findings to reveal at its upcoming press conference. It seems Curiosity's recent soil test didn't turn up anything particularly exciting after all. In other words, no Martian organics, no otherworldly artifacts, and no digging site for Elon Musk's future Martian colony, Starbucks. That's it for today's top stories. Tune in again tomorrow when...oh god.
