Recently my HP iPAQ PDA took a tumble when I was on an excercise machine and the screen is smashed and (being a touch screen) the unit is now unusable. I was shown the iPod Touch by a friend and it looked a very handy device to have. After doing a bit of research and joining this site, it seems that the Touch is not really a PDA replacement. Is that so? For example, it doesn't have a spreadsheet utility, nor indeed any Office-type functions other than a calendar. Can anyone confirm it owuld be useable like a PDA?
