The service manuals actually tell us quite a bit. For instance, neither one has wifi. If either one did, there'd be an antenna as a service part, and possibly a wifi daughtercard. The 600 has SD/MSPro slots, the 300 doesn't. Both are minor iterations of the current models. The 300 is a slightly downsized 505, minus card slots and mp3 playback. The 600 is a reworked 700.
