The E2 isn't a replacement for a regular digital camera. The E2 is an 
  effective tool that allows you to easily carry a digital camera with you everywhere. 
  Still, the question is why you need this? Let me give you some examples of who 
  might use this and why.
Real Estate - Agents never know when they will need to take a shot of a home 
  and they almost never take a photo in the dark. Why carry around all the extra 
  equipment and materials necessary to take an instant picture? Why carry around 
  notepads and file folders full of documents? With this camera you can take a 
  respectable picture of a building or lot and annotate it on the spot. You can 
  write all the necessary information regarding the property in your Visor. No 
  slips of paper and you capture your first impression accurately. Also, imagine 
  having a client that is looking for a particular property and you just happen 
  to drive by something that fits that description. Grab your Visor, take a picture, 
  write down your notes, and e-mail it to the client using your wireless modem. 
Architects/Designers - There are many situations where these professionals 
  have to go to a location where they are designing a base building or an interior. 
  Why not take the E2? You can take quick images and jot down your notes while 
  they are fresh in your mind. With an application like BugMe! Messenger, you 
  can even draw on the image and then e-mail it. Go back to the office and create 
  a PowerPoint presentation with the images. Then connect your Visor to the overhead 
  projector using the Presenter-to-Go and you can do a walk through with the other 
  staff.
Inventory - Not only can you use your Visor in conjunction with a bar-code 
  scanner, you could also use the E2 to capture images as well. You can keep a 
  record of not only what you have in stock, but what it looks like. This would 
  also work well for training purposes or for e-mailing images to buyers. 
Insurance - You could send out a claims adjuster with an E2 equipped Visor. 
  Take a few quick shots of the damage, write up your notes and send the info 
  right from the location to speed up the claims process.
The most unfortunate aspect of the E2 is not the image quality, but that there 
  aren't enough developers taking advantage of this technology and building tools 
  to support it. There are thousands of possible applications for the E2 right 
  now, but where is the software? The E2 does an excellent job for something the 
  size of a saltine and is certainly a promise of good things to come. Add all 
  the possible applications of a PDA/camera and you have a winning combination. 
Try not to think of what the EyeModule 2 cannot do for you, but with some imagination 
  what it actually can do.
