My IPod touch could use an external keyboard.
You know, kind of like my Palm Tungsten had, oh, 7 or 8 years ago???
..... not that it took Apple a coon’s age to add copy, cut and paste to the IPhone/Ipod Touch system .....
grrrr....
I’m a big believer in the market. The fact that there are no external keyboards readily available means not enough people want one to make it worthwhile to manufacture.
However, I have heard you can hack your own. As far as I know there is no serious technical limitation, especially since the Touch/Phone can be made to work with all sorts of custom accessories via the dock.
