The Mylo 2 has suitable Sony Headphones, unfortunately, they have a propietory port, so getting new ones is a bit of a challenge. Software is very stable, and much better overall user experience than the N800; though there is much more in terms of third party software available at this time for the N800.

If you want an entertainment device, but not be locked to Apple, the Mylo 2 is good here; very good actually. If you are looking for a tweak and work box, the N800 is better.

The iPod Touch is small, efficient for what it does, and nice in terms of the UI. Everyone has spoken about it in length, but I will say that it does make you wonder what other manufacturers have been doing. Its a polished piece of hardware.
