Software and charts can be easily updated in any configuration: panel
mount, dedicated handheld GPS unit, or PDA/laptop with a separate
receiver.

Which units provide more functionality is really dependent on the
user---which functions do you need? If you need units created for and
tested in cockpits, a dedicated unit with large buttons and an
outside-viewable screen works well. If you want terrain warnings,
color, maybe wireless weather, the PDA might be your choice. I wouldn't
use a laptop because cockpit space is limited and I nearly always have a
right-seat passenger, but if you often fly alone it could work.

Personally I'm saving up for a Garmin 430, and using an old Garmin 195
dedicated handheld. I find I have pretty much lost my investment in the
195, I couldn't sell it for a fraction of what I paid, but it still
works great and updates are readily available.

With the rate at which GPS technology changes, I was wondering if its better
to go with a receiver interfaced with a laptop or palm so that the
software/maps can be updated more easily. Is that a misconception? What
solution provides the most functionality?
