I see a lot of cynicism in this thread - much of it entirely deserved. However, from a broader perspective, this is undoubtedly a good thing - and not just in terms of "yay, I can play more things on my new console".
Why? Because it goes some way towards mitigating what was looking like a real risk of a "lost generation" of console games.
As older platforms have gone out of circulation, PC emulation has generally been there to keep titles playable. Hell, when my first-gen back-compatible PS3 died on me and I had to replace it with a non-back-compatible slim model, I was able to carry on playing my PS2 games from the original discs via PC emulation.
But there is currently nothing like working emulation of the 360 and PS3 and, given those platforms DRM measures and general hardware eccentricity, it seems reasonable to suppose that we are years, if not decades, from actually seeing it (if we ever do).
Neither 360 nor PS3 hardware was of the highest quality. The early builds of both consoles had high failure rates - legendarily so in the case of the 360 - and while later iterations improved matters somewhat, there's no getting around the fact that they both remained essentially disposable and short-lived devices built as cheaply as possible.
So at some point in the not-too-distant future (within5 years maybe? Certainly within 10) working 360s and PS3s are going to get harder and harder to find. And with no emulation for them, there is a good chance that a good chunk of the (huge) catalogue of games for those platforms is going to end up inaccessible to everybody bar specialist collectors.
Now, a good chunk of the library for both consoles is basically disposable junk anyway. Does it matter massively if a few iterations of Madden and FIFA end up lost to posterity? Not really. In other cases, games are being "rescued" via "HD remasters" for current generation platforms (which can, admittedly, feel like a rip-off), as has happened with The Last of Us and and as will soon happen with Gears of War and Uncharted. In other cases, developers looking to make money from their back-catalogue may put out PC ports. We've seen this rescue a few absolute classics like Valkyria Chronicles, as well as some more... shall we say... eccentric choices like the Hyperdimension Neptunia games.
But that still leaves a lot of games - including those which were subject to exclusivity agreements but didn't sell well enough to merit an HD-remaster - stranded. There are some good and noteworthy games here; Lost Odyssey, Vanquish, Eternal Sonata and so on.
Now, if the Xbox One has back compatibility all of a sudden, that means that we have at least a temporary stay-of-execution on all three of those games I just mentioned. Plus the fact that they're running on PC-like hardware keeps alive the prospect that we might see them running on "proper" PC hardware at some point further down the line. And if you care about preserving an unbroken history of gaming's development, then this matters. If you don't think that keeping that chain intact matters, then just ask the BBC how they feel about all of those Doctor Who episodes they threw into the trash.
Of course, we still have some PS3 exclusives that are essentially marooned; and that Cell architecture is going to render any kind of emulation, whether on general PCs or on current or future Sony console hardware, a bitch. That leaves some excellent games (the PS3-era Ratchet & Clank games were superb and a lot of Japan's output for the latter half of the last console cycle was PS3-exclusive) still stranded. But maybe this step from MS will put some pressure on Sony.
Hopefully, the PC-like architecture of the current generation will make back-compatibility less of an issue going forward, though there are still issues about the extent to which many games are essentially dependent on PSN or XBL network architecture.
