Hi Mike,
I have been looking into these a bit more. Chuck's suggestion
below looks attractive for the reasons he suggests and the fact you can read
the data from display for use with a map or in uploading a route when hiking.
I am going to buy the slightly more upscale version of the one he bought ("the
pro version") . This adds a true altimeter (press guage), useful for
mountaineering and also a true compass. I still like the idea of the Sony
where you don't need a computer to update the card directly, but the other
features make up for this.
The LI-ion battery life depends on how agressive they are, with the charge
voltage on the battery. The loss of capacity per chareg/discharge cycle depends
on the voltage used. You get more capacity at a standard 4.2V charge voltage
most commonly used, but the cycle life/battery life, is much lower than say
using a 4.1V charge voltage where the capacity is lower, but it declines at a
much slower rate per cycle, giving better logevity.
The SiGeRF III chipset used in the IgotU products, is not quite as sensitive as
the MK chipsets used in a few other taggers, but seems like the IgotU software
is better than some others.

Hi Tim,
You clearly have a good handle on things. One thing I forgot to
mention that is useful with the
IGotU 120 is that the software gives approximate battery life with
various acquisition rates.
I have used it for a couple days--turning it off when stationary for
extended periods and no images (e.g. nap?)
w/o recharging. The little cable thingie for USB charging is quite
small and I have a $7.00 USB 120/240 V charger
that gets used --just recharge the digicam batteries and the GPS at
night if needed--assuming I don't lug a laptop.
I am betting by the time the internal battery doesn't hold a charge
well (?5years) they'll be a GPS
chip in some other bit of gear. I see the new Canyon S100 has internal
geotag now for example.
I hope you get time to work on the auto-aperture mechanism. I'd be
first in line to sign up
for one.
Mike

The reviews on the Igotu 120 seem to have similar comments to your and
Moose's:
