Wondering through the forum I saw a few posts discussing stability of crystal/ceramic oscillators, timing errors, max current draw and so on..
Its always a pain to look through 500+ page manual for ATMega328 - today spent a few hours searching for internal voltage reference tolerances (which officially is 1.1v, in reality anything between 1 and 1.2, p.329)
Is there a reliable summary of this chip's properties on Arduino resource sites?

The datasheet is the last word, so haven't gone looking. There is a summary datasheet, only 35 pages vs. 567, but I think they leave out most of the electrical specs.
Antarctica? Wow! Are you on the "Arduino users around the world" map? http://maps.google.com/maps/ms?msid=203855014878637041865.00048bf511125d88d5fc7&msa=0
Thats right Jack, they've left out most of it. I'm able/willing to sense of main datasheet, unlike many other ppl, so this post is more like a suggestion to create such a summary..
I was just kinda impressed by this 10% discrepancy in reference voltage, something I hoped to be more accurate than my second hand bench multimeter (that I never bothered to calibrate 
).
Antarctica... Always wanted to visit )))
