Keyboard VS Stylus
For a long time, the keyboard versus
stylus issue was an issue between two different style devices. This
is no longer the case. PDA's tend to only be stylus based.
There are no PDA's will full size keyboards like were previously featured
on HPC's (Handheld PC's). However, the popularity of integrated
thumb board keyboards has shown up in many manufactures device designs.
The thumb keyboards don't replace the stylus input method nor can you type
on them like you would with a conventional keyboard, but the augment data
entry and navigation of the device.
Thumb keyboards are devices are primarily appealing to
uses that recognize the will want a keyboard style input method.
That may sound obvious, but users that find they use the stylus and the
on-screen keyboard to tap input, likely will find that a thumb board will
cut input time drastically. Users that use a jot (graffiti) or full
writing (transcriber, calligrapher) method, like won't find a thumb board
as useful for most input.
A stylus only device may give you more options if you
aren't sure a thumb keyboard is really needed but think you may want one. Most stylus
only devices will be much smaller, but if you do
decide later that a thumb keyboard may help, many devices will support
add-on thumb keyboard modules as well as full sized keyboards.
 Stylus input ... how?
