Apple has created a deck for car audio, but no one seems to have noticed. It has GPS. It has satellite radio capabilities. It has a built-in iPod. It has Pandora. Heck, it even has Netflix. Talk about your ideal road-trip companion. Best of all, it starts at just $629—or $499 if you ditch the GPS capabilities. That price is so low it’s blasphemous in the car audio scene. That’s right—we’re talking about the iPad.

If it’s so great as a car accessory, why have we rarely heard of it fulfilling this seemingly obvious purpose? The answer’s an unfortunately complex one, having to do with the iPad’s uncommon diagonal dimensions and housing complexities, the safety concerns it creates for the driver, and perhaps most importantly, the danger it presents to the car audio industry. 

Nobody likes a know-it-all, right? Well, unless they need to know something that know-it-all knows. And on the flip side, some people are just naturally helpful and want to offer advice—but unless your name is Miss Manners, you might not get asked. 

Aardvark is a fun and free service that matches up question askers with confident answerers. It brands itself as a “social Q&A,” and it’s perfect for those times when you need a subjective opinion (“What’s the best Twitter app for iPhone?”) rather than an easily Google-able fact (“How much does Twitterific cost?”). Plus you get to give your two cents on other people’s queries while keeping your privacy intact.
