Yeah, me too.  But all the little all-in-one IC temperature sensors  
(lm335, etc) seem to only be good to about +/-1 C (and they're proud  
of it!)  It's particularly annoying since 2C pretty much covers the  
ground from "uncomfortably cool" to "too warm" if you're talking about  
something like a thermostat.  (Of course, that may be a precision  
thing rather than an accuracy thing...)
