All the IPAQ 3600/3800/3900 most of us have been flying with for years
have the same screen res.
470/240 is not a problem in fact it makes the screen refreshes faster
than units with higher res. but same speed processors.


(they also have small battery capacities from what I can tell)

Thats why you wire them into the ships power like a regular IPAQ
solution.


Since none of these "roll your own" systems are going to be IGC-legal
for badges/records, why not simply use an IGC-legal external computer/
logger with its own GPS (a la the ewMicroRecorder or similar)?

Most flights flown can use the software generated IGC files to post to
OLC which is what 99% of flights are.
If you want to get badges or records then you will have a full IGC
logger in your possession anyway


Ditching the GPS component from the PDA/PNA means a simpler device
with a much lower power consumption level. *Seems to me that there are
a lot of non-graphical (but IGC-legal) loggers and flight computers
out there, and most work fine. *Its the moving-map/navigation aspect
that needs work - so why not concentrate on that?

The integrated GPS uses a lot less current than an separate device.
Have you even seen the latest versions of XCSOAR?


And If your GPS fails, you _do_ have charts in your plane... don't
you??


Charts LOL of course and they are all up to date as well.
