There was lots of grumbling when Apple obsoleted legacy speaker docks by moving iPhone and iPad to the Lightning connector, but a company called Auris saw some opportunity in that grumbling. It has a Kickstarter project called Skye that is essentially an AirPlay receiver for your legacy 30-pin Dock speakers. Slip it on your Dock the way you used to slip on your iPhone, and you then send music from your iPhone, iPad, Mac, or PC (through iTunes) wirelessly. Android and Windows Phone are also supported through DLNA. It's Wi-Fi (rather than Bluetooth), so range won't be an issue in most settings. Auris is trying to raise US$56,000, and has already raised $21,800 in just the first day. Early backers can get a Skye with $64, $69, $74, or $79 (it will retail for $89). It's a pretty cool idea, so check it out.
