NXT2WIFI Now available

The NXT2WIFI Sensor (could you call it a sensor?) is now available!  After a successful Crowdsourcing start, our very own Daniele Benedettelli now has the NXT2WIFI available.

What does it do I hear you ask?  Well, let's suppose you want to control your NXT robot from your iPad... or your Android Phone... or your computer?  In fact, any device that can talk to the Internet, can talk to the miniture web server that is the NXT2WIFI.  Want your robot to talk back to the Internet?  (Think Twitter posts or Sensor data), well the NXT2WIFI can do that as well :)

Specs:
  •   2MB Flash Memory onboard to store rich webpages!
  •   Transceiver 802.11 b/g/n Wi-Fi certified MRF24WB0MA
  •   3,7V 1000mAh LiPo onboard long-lasting battery
  •   Integrated RTC 32,768 Khz quartz onboard
  •   2 serial ports for communication: RS485 to NXT port 4 and miniUSB to computer)
  •   56 x 72 x 18 mm, 50 grams
  •   8 LEGO-compatible mounting holes
  •   BUILD HUGE ROBOT NETWORKS!
  •   CONTROL YOUR LEGO ROBOTS WITH ANY BROWSER-ENABLED DEVICE!

Really cool, and I would be interested in it but I have to ask why would anyone build a WiFi adapter that must phone home/be activated? That does not make any sense to me and is an instant No Go.
"NXT2WIFI needs to be activated the first time you use it, and every time you updgrade the firmware, otherwise many functionalities won’t work."
Can anyone explain what this accomplishes (for anyone)?

I think the activation is a thing from the company who makes the chip: openpicus and not from danny.

maybe you find some more info there http://www.openpicus.com/

Activation is free and takes 1 second. Why should this be a "instant No Go"?
This helps against product fraudolent copy, just as for software.

Many reasons to be a no go. For one, supporting a company with OPEN in its name, that requires a phone home is a joke, I can't take them serious. Two, not every place has internet - specifically the place my LEGO robotics groups meets does not. Activation may be free in some places, internet connections and equipment are not. But again, it is more of a principal thing - i've seen it fail too many times, and have no intent of asking someone if it is OK to use the device I purchased. Users who use Apple products probably have no problem with this, I do, and there are alternatives.
