The Year of the Personal Navigation Device?

Here's another major theme at this year's CES: personal
navigation devices. Looks like TomTom
really started a trend with their touch-screen only form factor. Here are just
three of the many new offerings. These three are from
Sanyo (EasyStreet),
HP (it's actually just a new form factor iPaq)
and

Polaroid. They are usually Windows CE based.
