If you do now want to edit, just use the data to display a map (and
perhaps do some routing, etc ...., you need less data (no created_by
or other useless tags and things like highway=residential can be
translated to some index into specific lookup table)

GpsMid (app to display OSM maps on a cellphone and route in them) can
take ~72Mb bzipped dump and produce ~36Mb .jar with the app and
(almost) all the "usable" data in the OSM. So maybe there is some way
to get 6.2 GB planet dump and produce some ~3Gb file that would
contain entire OSM in a manner that would allow easy displaying and
perhaps routing. Though nobody have written such program yet :)
