Neil, thanks for the great information. Our current plan is to run a
pilot with 7 surveyors spread all over the country. Here's the
shopping list we've put together, would love to get feedback from the
group.
14 phones http://www.integrontech.com/ProductDetails.asp?ProductCode=HTC-G2-B&click=2
7 car outlets http://www.amazon.com/Duracell-813-0291-07-Pocket-Source-Inverter/dp/B000U0M7PG/
7 netbooks http://www.amazon.com/Toshiba-NB305-N410BL-10-1-Inch-Royal-Netbook/dp/B00303G9FO/ref=sr_1_4?ie=UTF8&s=electronics&qid=1280280536&sr=8-4
7 solar batteries with HTC adapter tip http://store.solio.com/Classic-i
We plan to procure outlet adapters and surge protectors locally. (This
goes against Neil's advice, which makes me a little worried.)
Thanks for the help, Andrew
