i'd call this "project evolution" :)

wpwrak that link is for YOU!
<rjeffries>
wpwrak which MCU are you using for your current project?
<wpwrak>
right now, an avr (attiny87 or 167
<wpwrak>
but depending on the occasion, i also use silabs c8051f3xx, microchip pic, and maybe soon the little arms from nxp

NXP does have a clever ARM M0 dev board. Got one free at a show. I want to get my hands on an ARM M0+ (VERY! low power in ac in ntive and sleep-y states) coming in next 30 days supposedly.
<wpwrak>
that was an unusual way to mistype "inactive" ;-)
<wpwrak>
so far, i didn't need any of the ultra low-power stuff. usually, a few uA in standby are quite bearable. even a CR2032 lasts for years with that :)
<wpwrak>
besides, what really matters usually isn't super-low standby current but how often you have to wake up while in standby
<rjeffries>
wpwrak agree, it is all about duty cycle. the radio is typically the power hog in a wireless sensor node, but the total power budget is worth minimizing. Ti430 is another decent option.
<wpwrak>
yeah, they're heavily marketed towards low power
