I want to start off by saying that I'm surprised The Verge doesn't have a review for this up yet. But anyway, I've got one and totally love it:

I will start off with the build quality. Bose always has a nice professional design. I have the standard version, which lacks the chrome trim or the leather cover, neither of which are necessary. The folding cover is very nice. It's nice to have something to protect the system while it's in my bag, and it's a great stand as well. The speaker is a nice size, not too big or too small, and it's easy to carry around. It has some weight to it which helps add to its solid feel. The big buttons on the top and the status light on the front are also a nice inclusion.

Connecting devices is quite easy. However, when multiple devices are synced with it it can take a few tries to get it to connect to the device I want. I just need to make sure there aren't other devices nearby with bluetooth turned on that are already synced with my speaker. The last used device always syncs first, and it connects quickly. I haven't experienced much dropout, but I do (rarely) experience interference from other bluetooth devices (my Magic Mouse). Hooking up a device to the included aux cable is also incredibly easy, just plug it in and hit the aux button.

And finally - the sound quality. I'm no expert on audio, but I am very happy with the quality. For its size, the speaker can reach very high volumes and the speaker produces good bass. I've listened to a large variety of music on it, and everything sounds great.
