We said we've been "watching" the W950 for a while even back in early 2006, but Sony Ericsson's finally making it available for online purchase. Not subsidized by any provider, the W950 is going to be the king of smart Walkman phones in both cost and features.
The phone has 4GB of internal storage, TrackID Music Recognition (record a few seconds of a song, then ID it later), Bluetooth, A2DP, Push Email, Quad-band GSM and UMTS, and runs off of Symbian. The Walkman software is 2.0 and goes all on top of a 2.6-inch touchscreen display. No price yet, but should be available soon.
