My old technology Garmin GPS III+ takes about one minute from power-on
to satellite lock. Your Axim must be some fine piece of work.

But its a *DELL*...

I don't have anywhere near as fast response with my Magellan Roadmate 500!
Many times I've plugged in the Magellan, put our luggage in the rental car,
and been out on the highway for five minutes before it locates us. Not
great if you're not familiar with the area!

And your GPS is a GPS all the time. Mine is not...I have a GlobalSat
SD-502 SIRF Star III receiver on a SD card that I only plug in when I
need it. When the protective case is on the card end, the entire
receiver (which integrates 512MB of RAM, so all my nav software and
maps are stored on it) is about the size of a cigarette lighter. When
it's installed, it adds maybe 1.5" of height and no extra thickness to
my PDA.

With my Garmin GPS V, how long it takes to sync up with the satellites
depends on how long it's been off, and where. If it's been off for
several months, it takes a couple of minutes to sort things out. Or if
it has moved a couple of hundred miles down the road since it was last
powered up. If it was on recently and in the same location, it syncs up
in 30 seconds or so.

The point of aGPS is that the cell site sends the phone, in a couple of
seconds, all of the info it needs to do a location fix, and it only
needs to pick up relatively few bytes from the satellites to get the
fix. Also, aGPS can also use triangulation with the cell sites along
with the GPS fix, particularly if it cannot "see" enough satellites.
These were requirements for E911, but come in real useful for
applications like VZ-Nav.

It just never seems that fast when you're waiting on it.

I'll be itching to try a demo of it, but the only potential downer for
me is I'd have to re-rig my car to get the audio output, external
power, and mount set up the way I would like it. But if Verizon
integrates aGPS with the traffic info feed that some devices use now
(hello, data plan ) into a proper PDA-replacement smartphone with a
decent-sized screen, I could see buying into that easily.
