Sony Ericsson W800 & Sony Ericsson W800i Walkman Phone

I just wrote a guide about the Sony Ericsson K750i - a great phone. In fact, my last two phones have been the Sony K700i and the Sony K750i... and I give a 5/5 rating for each. The Sony W800 and W800i (which are the same phones) are really the same phone as the K750i but with a slightly different interface (the Walkman technology is the focus), a white body and the W800 / W800i comes a 524 MB memory card (while the K750i comes with 64MB).  That said, all are excellent phones and the determining factor will probably be price. Rough estimates of the past few months on eBay suggest:

New Unlocked Sony K700i  = $175-$200
New Unlocked Sony K750i  = $325-$350
New Unlocked Sony W800  = $400-$450
