Let me give some background of where I am coming from. I owned the first RIO MP3 play, one of the first CD based MP3 player, the first DVD MP3 player, one of the first in dash MP3 players, a 1st Gen iPod, a 3rd Gen iPod, and a few random USB Thumbdrive type MP3 player. I currently carry an iMate Jam PocketPC phone, and have used a Samsung i-730, Torq P100, Siemens SX66, and a Sprint PPC-6700 lately (among others).
I love my Jam for what it is. Its a good phone, and a great PDA. As a media player? Not great. It works, but without the dedicated interface of even the cheap MP3 players its not the most user friendly device. The interfaces are getting there though. Devices like the Samsung SGH-i300 and even the much maligned (deservedly) Motorola iTunes phone, are getting there. Add a few dedicated buttons, a navwheel/pad/joystick that works, and some nice Bluetooth headphones, and you are there.
I think that's that's why everyone keeps clamoring for an Apple iPhone. They have proved they know how to make a good interface. I also thing that's why they aren't rushing one out the door. I don't think you can make a All-In-One device with as clean an interface as the iPod. If someone does though, I guarantee I will buy one.
