The Wave Cradle is a novel solution, made of aluminum and rubber that does one thing. It redirects your speaker's audio, acoustically rather than electronically, towards the user. This great for FaceTime as well as listening to music.
The cradle has a nice grip that keeps a naked iPhone in place, as well as one in a relatively flat case. The Wave Cradle comes in two models, a simple one-piece model (plus the cylinders that support the iPhone) and a more stylized two-piece elevated model. I actually prefer the lower cost ($20) one-piece model, as it is more subtle compared to the $29 model. I could see the two-piece model being valued as it minimizes vibration and raises the view of the iPhone. Black, red, and blue cradles are available with more colors were shown at MacWorld.
The makers do several things right. The unit comes fully assembled, whereas I could see some companies shipping it in pieces and making the user assemble it, to save on production and shipping. Speaking of production and shipping, the Wave Cradle is made in the USA and USPS shipping is FREE!
