It used to all be so simple: Cybershots for photos, Walkmans for music. But recently Sony Ericsson's phones have been teaching each other tricks, leading to the arrival of two seemingly identical new handsets: the W902 and C902.
Both have a 240x320 screen, HSDPA, A2DP Bluetooth, an FM radio, nine hours of talk-time, an accelerometer for flipping the screen round and, crucially, a 5MP camera that flaunts autofocus, LED flash and the ability to record QVGA video at 30fps.
But having played with the W902 prototype that's just landed on our desk we've picked out their subtle differences. Firstly, there's memory: the W902 comes with an 8GB M2 card, whereas the C902 makes do with slightly more internal storage (160MB to 25MB).
Secondly, the W902 has a slightly bigger screen, though this is mainly because the C902 flanks its display with flash illuminated shortcut buttons for camera tinkering.
And, finally, the W902's music-focus sees it pack the latest Walkman Player 3.0, dedicated playback buttons and some 'premium' HPM-77 headphones (worth, ahem, £15). The C902, meanwhile, makes do with some budget earbuds and a different music player that's, in our experience, not a million miles from the Walkman offering.
Which all means it'll mostly come down to looks. They're certainly both nice 'pieces' to slip into your gadget holster, but the C902 just edges it here with its silver-striped trim and nifty sliding lens cover action. Look out for our final verdict on the W902 very soon – if you have any more questions about either phone let me know below and I'll try to answer them.
