Palm

There is only one large print program that I am aware of for the Palm Operating system.  TealMagnify by TealPoint Software allows the user to have 2x magnification in any program on the Palm.  The downside, is that the magnifier deactivates when you interact with the program that you are magnifying.  The images below show the views possible using the TealMagnify Program.  The cost of the program is $11.95.

There is also a 2x magnifier which can be clipped to the PDA.  The Magnifico (pictured below) is a $29.95 item available from Office on the GoGo or Independent Living Aids
