Hello Stuart
Thought I should mention WildKeys experience with handhelds....around 1200 students have now used our initial products which focussed on wildlife identification...we try and capatilise on all the benefits that a handheld device can provide and make use of the high quality screens (for images of wildlife), gps (for recording location), camera (to take image of species) and of course the mobility of a device (when you are chasing a butterfly it comes in handy!)...to date we have focussed on PDAs/smartphones as devices (mainly due to the need for GPS)...this has advantages in that you don't need web access but obviously involves uploading and downloading to/from the device...for more on the use of handhelds for wildlife id see
www.wildkey.co.uk and click wildkey in action....interestingly as we have diversified (wilddata - teachers create their own recording forms) and wildmap (teachers creat their own web trails) we still rely heavily on gps....as such until phones tend to have GPS integrated as standard we still see a role for PDAs/EDAs in the forseeable future
...if you want a copy of our research findings let me know
