Perhaps not four or five devices but "three or four" seems reasonable:
- BlackBerry/iPhone
- Netbook or notebook
- eBook reader
How many people also carry an extra "work phone?"
Sure, convergence is good: my BlackBerry replaces two devices, a Palm Tungsten and a Sony T68i cell phone.
I used to carry a paperback book with me, or several. Now, I carry a Kindle and no books.
I'm not carrying any more than I used to.
I've just replaced "conventional objects" with electronic "devices."
