I had a similar experience a few months ago, at jury duty, with my brand-new Panasonic cell phone. Id expected to be able to use the phone until my panel was called, but the phone was confiscated on my way into the courthouse.
Now, I can live without a camera, but I cant live without a phone. And a PDA you cant use at work is more like a paperweight.
Ive heard that this trend of confiscating and banning such devices is expanding in North America, Europe and Asia. It creates a serious problem for people who have become addicted to them to manage their lives and communicate with the outside world.
In my case, I had to retire the $400 Panasonic phone, which was only 3 months old, and go to a Motorola phone that didnt have a camera. A huge waste of money, but the Panasonic phone didnt work particularly well, so I dont miss it as much as you might think.
I did really like the idea of having a camera that was always with me, and clearly, in Japan in particular, getting rid of these combined devices will be nearly impossible. What is needed is a modular approach to the solution, so you can give up the camera but not give up the phone. Strangely enough, Handspring, now part of PalmOne, at one time had a technology that would do this.
Handspring created something called a Springboard module, now discontinued, which allowed you to upgrade a Handspring PDA with accessories such as a camera without buying a new handheld computer.
These days, the best way to do this is to get a PDA that has a Secure Digital Input/Output (SDIO) slot and get an SD camera module. But the implementation isnt as well-integrated as Handspring was, and the placement of these SD slots often is hardly optimized for camera use (and some wont take accessories such as cameras).
In addition, part of what makes the integrated devices so attractive is that they are very easy to use. The devices are designed with the camera in mind, so the buttons you use to take and manage the pictures are often (granted, not always) intuitive, avoiding the need to carry the manual with the device.
This means that the camera should be designed in but be removable, rather than a third-party add-on, so that usability doesnt become a problem. In addition, a designed-in solution often looks better, and these devices are often as much personal statement as they are tool. In short, if its ugly, people wont buy it.
