External GPS?
I am hoping that those who buy the non 3g GPS can plug in an external GPS receiver.
A bunch of interest in this product is from the aviation industry, to turn the iPad into an electronic flight bag.
Due to the banking of the aircraft during flight, an external mounted GPS antenna will work much better than an internal one within the iPad. Also, cell phones are not suppose to be used while in flight because of FCC rules (I think) which on the iphone also turns off the GPS be default in "airplane mode."
I am hopeful a plug in GPS unit (does the iPod touch have one?) will allow a GPS to be used with the wifi model only, and those who do not wish to subscribe to 3g service.
I think we will just have to wait and see.
