Unless you are downloading maps from the computer to the GPS, a GPS unit can be expected
to transfer ... maybe ... a couple of *kilobytes* of information. Not "megabytes of
information." Even if you are downloading maps, 115 kbps is fine ... you only have to do
it once.

I want to use a GPS to record the location where I took a picture. Do any of
you know of one that records the location, and time when the waypoint is
marked?

The Garmin GPS12 does this, I have one. I would like such a feature with
a camera, perhaps also with a compass, so the EXIF record could include
where and in what direction the photograph was taken; the again perhaps
a notepad would be better, certainly cheaper.

even if I didn't mind shutting the computer down to connect, and then
disconnect the GPS (which I DO mind)

I can understand the reluctance to use such a low speed connection for
large amounts of data, but since changing the data would be infrequent I
do not see at as a major disincentive. AS for switching the computer off
to connect a serial device, WHY? I regularly connect and disconnect
serial devices without switching anything off to do so, maybe it was
important in the old days but modern systems are for more resilient.

No it does not, my PCs at home and work do not; I regularly connect and
disconnect their serial ports.

Why abandon it? It's adequate to the task and it's the most compatible
interface around.

Not at all. 90% of the problems people reported with communications
before USB and Ethernet became common were caused by incorrect serial
port connections, or setup. It's a SLOW and cumbersome method, and
requires power cycling to connect and disconnect. It's fine for
connecting a keyboard, but I wouldn't deal with it again for all the tea
in China.
I certainly won't buy another GPS receiver until they ditch the ancient
interface.

Where does this "power cycling" thing come from? I don't powercycle anything
when connecting and disconnecting RS-232 devices. This is just plain wrong.
I've been using RS-232 since the mid-80's, and none of the equipment needed to
be shut down to connect or disconnect an RS-232 device.

It was entirely pertinent. You appear to favor change for the sake of
change, so discarding AA batteries simply because there's something
newer would make sense according to your reasoning, just as you seem to
wish to discard serial interfaces just because there is something newer.

I attempted to use it once, but couldn't decipher the software so I am
not sure if the serial port was correctly configured, or not. The
software was an example of software written by people who knew exactly
how the system worked, but weren't ABOUT to let the user in on their
secret. I discarded the idea of loading localized databases after a few
tries.

My Palm Pilot works perfectly over the serial port, and it did so from
the instant I plugged it in. There was nothing to configure.

I think you have a software problem, not a hardware problem.

I love the GPS, and enjoyed using it on vacation this year (Alaskan
Cruise), and would love to have one with the moving map, but the idea of
trying to load several megabytes of data to it over a serial connection
is just NOT something I would undertake.

There are always paper maps.
