What's inside a Lytro camera? (teardown)

Curious what's inside the first Lytro digital camera? You can check a 37-picture teardown at Wireless Goodness (you can also see them with PicLens). One surprise they found inside the camera is a Wifi/Bluetooth chip by Marvell (currently not used). [via TechCrunch, Techmeme)

The fact that this tiny little thing has built-in Wifi/Bluebooth may perhaps call into question the excuses/explanations by some camera manufacturers as to why they don't include Wifi/Bluetooth in digital cameras?
