I use mine every day. It's one of the best electronics investments I've made in years.
It's an iPod, so I get to store and listen to music and other audio anywhere.
The iPod touch has built in calculator and calendar. The clock/timer means I can set an alarm and not exceed time on the parking meter.
The note taking function means all kinds of short notes taken during lectures, at the archives, reading books and watching TV are always with me.
I get email, browse the web, view YouTube videos, download podcasts including those from TNA, and do so anywhere there's an accessible wifi connection. With my wifi at home I can access these anywhere in the house. An increasing number of public institutions like LAC, TNA, airports, and libraries also provide free wifi connections.
I've discovered applications that allow it to act as a reader, with ebooks I can borrow free from the local library which also offers free audiobooks.
Other applications downloaded give me a dictionary, shopping list, Air Canada link for my flights, newspaper access, and much more.
It slips into my shirt pocket and I forget it's there until I need it. It has helped lower my blood pressure and frustration. I turn time waiting for medical appointments and at the airport into useful time listening to or reading useful background.
Yes, I lust for an iPhone It has a camera and GPS and you maintain internet contact anywhere the telcos offer wireless service, but not for me at the prices they charge in Canada.
If you're looking for a last minute gift for a genealogist, or anyone not technology adverse, an iPod touch would be right at the top of my suggestion list.
Incidentally, this post was composed on my iPod touch.
