Learning to aptly handle your PDA or the Cell Phone is not always easy for you need to master the keys on your keyboard.  

Data entry into the memory is another problem with those small keys but I believe that the problem can now be countered using this jumbo keyboard pictured above. Surprised you may be, but that is a keyboard for your cell phone which comes across as a projected image using infra-red technology through a mobile black box. Sighted in Australia in a Hutchison 3G store, all that it requires is a Blue-tooth enabled handset and a flat surface ahead.
