dflat,

this one is the new unit and it is VERY expensive. It does also offers a lot of functions which are duplicates of what you can have on software on the iPhone and to fully take advantage of the unit you need to plug it to a PC or Mac so you loose the portability.

I have the previous version, and I should have been more clear in my previous post. Here is the unit.

Much smaller, thus portable.
