First off, please call it iPod Touch. itouch sounds...just a bit childish plus this will drive many Apple fanboys crazy.
Anyway Dataviz should be releasing an Excel/Word/Powerpoint bundle for the iPod Touch/iPhone. I have their Documents To Go for my Palm Tungsten and its quite usefull...expecially with the add-on full size keyboard I bought. Sure I don't use it anymore but its a great software for such a little thing.
When they do release it for the iPod Touch, it should be good and all...but without an actual 'physical' keyboard typing may become a pain. Since the new iPod Touch does have Bluetooth inside, some smart company may want to jump on creating a bluetooth keyboard and driver for the iPod Touch and iPhone. BUT don't yell at me if this is already in development (which it probably is) and its important to note that knowing Apple's policies/tricks, getting an external device to collaborate with the iPod Touch may be a bit of a headache. 😀
