I regularly do 0603 with tweezers/magnifying glass/Metcal iron with
fine tip.  I once had a board with 0402 parts.  ISTR doing a little
manual rework on it, although not much involving those small parts
thankfully.

The EIA maintains a parallel nomenclature defining the size of SMT
passive parts.  I belive it may be metric, and may be more common in
Europe (although I could be wrong).  In America, we use the more
informal nomenclature 1206, 0805, 0603, etc. which is common in the
industry, but doesn't have a standards body defintion behind it (as
far as I know).
