I do all these on an IPAQ but all mine have been Compaq/HP so I've
not used others to compare. I currently have an Hx4700 with built
in BlueTooth, email and web via the mobile phone (the phone just
wakes up and does the job), TomTom navigator with a plug in GPS
and lots of big SD cards to carry lots of other things. The 640x480
screen is really good when I dump pictures to it.

The GPS is fun as it will give me spoken directions to walk to
a destination which is wild when you are meeting up for dinner
in a strange place and the thing in your pocket is telling you
to turn left/right.

I have the compilers and wrote some of my own stuff. I've become
reliant on my own blender s/w but my deco stuff has been squeezed
out by diving the VR3. I am currently trying to dump the details
out of VR3 download program to keep a working copy of my log on
the little beast.

Ooooooo.
Any details?

I use a  O2   XDA2  PDA/Phone

This runs  Pocket PC (windows)

I use  Memory Map ( http://www.memory-map.co.uk )
 which runs  Ordnance Survey maps for land based stuff, (this is not a
Sat nav car system  its mainly for walking)    this can be linked into
a Bluetooth GPS recever
 It allows you to run Map Tech  marine Charts on your PDA
I use this for Plotting Dive sites   etc  see mamory map site

 you can get  V-planner VPM based software  www.v-planner.com   for
PDA
I havent tryed it out yet

 there are various other Dive progs avalible freeeware  to  loads a
dosh
 loads a log book software etc

I would like  to run my VR3 on it but not avalible yet

Garmin makes two PDA devices that might be of interest.  Both are charting
GPS devices and both will take either land road maps and charts provided by
Garmin.  I assume, but have not confirmed, that maps and charts for Europe
are available.  I have the maps for North America and the charts for S.
Florida.  Both are as good as anything on the market, but probably no better
than what is available from other manufacturers.

IQ3600 - This is a Palm operating system device and was my original GPS/PDA.
It takes an SD card, but may or may not have SDIO capability.  It is neither
bluetooth nor wifi compatable, which makes the question of the slot a bit
more important for those that wish to connect from it.  Possibly the biggest
single advantage of this unit over the one discussed below, is that there is
a free Tide Chart program as well as a free download program for my Citizen
Hyper Aqualand available for Palm devices.  I've found nothing comparable
for Windows Mobile devices.  My unit came with Garmin's proprietary City
Select software, but did not come with the car kit or travel set.  The car
kit includes a weighted mount, speaker and car power plug combination that
is absolutely necessary if you're going to use it for auto navigation.  The
problem is, the thing is a power hog.  It won't run but a couple hours, max
without external power or a charge.  The cradle that comes with the unit
sucks big time, but the travel kit works fine.

IQM5 - This is a Windows Mobile, second edition, version of the unit above.
It does everything the one above does, plus a bit.  It also uses an SD card
and is SDIO compatable.  It is also comes with bluetooth, but not wifi.
Personally, I have little or now use for bluetooth.  My new notebook
computer has it, but nothing else I own does.  So far, I've not been able to
synchronize the two devices via bluetooth.  The downside, for me, is that
there is no tide tool or Citizen HA download program I'm aware of for
Windows Mobile devices, at least no free ones.  Tide tool is an
exceptionally useful tool for me.  The unit is not wifi, but there are wifi
SD cards available that I understand work with the unit.  I don't have one
only because I'm waiting on a change to Windows Mobile to allow the SDIO
port to handle both data storage and wifi and the release of SanDisk's
combination wifi/256 meg data SC card that the company reports is being held
up by Microsoft's failure to address the dual use issue with it's Mobile
software.

My wife has a recent model of the HP IPAQ.  It is not a GPS, but can be
mated with a GPS adapter.  It takes an SD card and is both wifi and
bluetooth equipped.  What it does, it does better than my Garmins, but, like
I said, it's not a GPS, a feature I won't live without.  I travel
extensively.  She doesn't.

If anybody out there knows of a Windows based system including cables,
software ,etc. for downloading from a Citizen HA, I'd love to hear about it.
While I'm quite fond of free software, I would probably pay a reasonable
amount to be able to download to my PDA and leave my notebook computer safe
at home.  I'm also interested in something to take the place of Tide Tool
provided it's available for the US.  Knowing the tides in the UK isn't real
useful for me.

Or get a combined handheld and phone (but bluetooth works great if you prefer
separates).
