Now that it's available as a carrier-subsidized option, the w810i is a bargain.  Who cares if it's a few years old?  The 810 packs SE's best-in-class Walkman software, a 512MB Memory Stick expandable to 4GB, quality earbuds with a 3.5mm adapter for your favorite 'phones, and perhaps the best 2MP camera available in a phone.  I've been using the import-version w800i for awhile now and it sounds as good as my iPod.  If you want something newer, try the K790/800 series of phones; they're not Walkman phones, but feature an excellent music player and 3.2 MP camera.
