So, want a digital camera with or without Wireless LAN? That’s a question you’ll need to answer when choosing between this P3 and P4, because they’re identical, except for the fact that the P3 has Wireless for a connection in b/g to a printer or a PC. Both devices offer 8.1MP, a 3.5x optical zoom and 23MB of internal memory, all tucked in a 92×31x61mm and 170g casing.
