Awesome!! Can't wait for the schematics and IDE to release. I'm gonna order some Attinys in anticipation
Also regarding the power usage. I seem to have some problems with by arduino (I think I blew the FTDI chip). So i couldn't program it to set pins high. I did put an empty chip in (IDLE program) and got about the same power usage as you did: ~30 mA.
I am going back to the university in a couple weeks. I plan on just doing power testing an Atmega 168 bootloaded with Arduino on beadboard. This should give a better comparison between power usage on Attiny84 and Atmega168
