Last week we gave away a TwitterPeak device on a whim. It turns out giving stuff away for free is popular, so we're going to keep doing this every Friday until we forget to keep doing it. Up this week was going to be a shiny new pair of Facebook cufflinks. But at the last minute Sonos stepped in and is generously offering to give one of our lucky readers a $399 Sonos ZonePlayer S5 all-in-one wireless music system.Want it? It's yours. Just do one of two things: either retweet this post, and make sure to include the #crunch hashtag, or leave a comment below telling us why this device must be yours. Please only tweet the message once, anyone tweeting repeatedly will be disqualified. We'll pick a winner tomorrow afternoon and contact you for more details. Anyone in the world is eligible. Sonos is generously donating the device and covering the shipping costs as well. If you aren't lucky enough to get the free one, you can buy the S5 for $399 here.More details on the S5 in the demo video below. You can also read more about it on CrunchGear.
