Today I picked up the Sansa Connect from Sandisk. So far, I'm totally impressed with this device. It runs embedded Linux with an interface written in Mono. The really neat thing about it is its built-in wifi connectivity. It does what the Zune is missing - it streams music off the internet. Currently it only streams from Yahoo Music, not sure if there are plans for any other services. Also it has 4 gigs of internal memory and a micro-SD slot. If you subscribe to Yahoo's Unlimited service - a flat fee per month - you can tell the device to download the songs and albums you hear while streaming. When there's no wifi signal, you can play the music that's stored on the device. It also can view pictures from flickr and you can trade recommendations with your Yahoo Instant Messenger friends.
The sound quality sounds great so far, and so far I haven't been able to put much of a dent in the battery after a couple of hours (it was charging before that). This thing definitely gives the iPod and everything else I've seen a run for its money.
