Look at both formats, side by side. At first glance it doesn't appear that one format could replace, or be used alongside the other very easily. Upon closer examination you begin to see the advantages and disadvantages of each format, as well as possibilities on how they might work together.
First of all, the HP 95LX has a size advantage. It's almost three times smaller than most desktop day planners. The 95LX can also remind you of appointments with its alarm functions, and backup files to another computer, providing security in case of data loss or theft. If you've ever lost a day planner, this advantage becomes very attractive.
The day planner has its advantages. If you need to copy a phone number or address for someone else, it's very easy to tear out a piece of paper and write on it. Also, day planners have storage for pens, paper clips, credit cards and other handy items.
It's tough to compare all the characteristics of the two formats because the way people use their day planners and 95LXs differs widely. It's even tougher to get people to change the way they do things unless the benefits are great (and the effort involved not so great). With that said, let's take a look how we might use the 95LX as an electronic day planner.
