The 32.768 Khz crystal is for an internal real time clock (RTC).
Give sparkfun a break on the pricing. That micro is almost $6 in 100 unit quantities from Digikey. They are selling you a unit ready to program. You didn’t have to tune the RF section or learn how to reliably solder a 0.5mm pitch QFN.
Being the cheap bastard that I am, I decided to make my own RF boards based upon the this same chip when it was announced last fall. If I could just get working on making kapton stencil, I could solder the puppies down and start slinging some code.
As a side note, the Contiki OS should run on this chip with a little modification. Contiki did the heavy lifting and already ported their OS over to the Atmel Ravens boards (which were basically a 2 chip precursor to this chip). IPv6 over wireless ! You could get a Raven USB stick to bridge from a computer to this board.

Anyone know where I could get a prepaid SIM card in the USA that can do data and not just voice? I really can’t justify a $30/month data plan for a vehicle GPS tracking/theft recovery system. I could justify making one with a pre-paid SIM, though.

Pogo pins rock! Why place a huge 0.1" 6 pin ISP header on your 1"x1" sensor board when you can place 6 pads and use pogo pins to program your atmega.

Yea, I was also able to pry off the end cap and string several blocks together to make a 24 pin and 30 pin terminal block. Just be careful. I snapped some of the pins that hold the end cap off by prying to hard. Here is a pic of the final parts soldered on my board.

The example stepper motor control link is broken. Anyone know where it went to?
No public wish lists :(
