I conducted my own preliminary investigation using my 16 GB WiFi iPad 2 and a number of supporting apps and gadgets, including a Verizon MiFi for an Internet connection.
Once on the scene of the accident I accessed my DropBox iPad app to pull up my client’s file and compared the photos in there with the scene in front of me. The iPad shined in this endeavor as the two years that had passed from the accident to the lawsuit had not been kind to the accident site. The paint used to mark points of impact and the location of the body had nearly faded to oblivion, so my “fresh” iPad photos became my landmarks.
I used Voice Recorder HD with DropBox support to record a brief statement from my witness while simultaneously taking notes in Penultimate using a Kensington Virtuoso stylus rather than my pudgy fingers.
