PDAs

PDAs are the ultimate luxury tool for time management, carried around by early adopters of technology.

Is it realistic for me to buy a PDA?

However, you may be surprised to discover that there are several inexpensive models out on the market, making them accessible to anyone these days.

What is a PDA used for?

Having a PDA is like having a computer in your pocket. They come with all kinds of software. Much of their software is oriented toward time management, hence their primary use as time management/scheduling aids.

PDAs also come with games, which may make you less productive. If you are disciplined, though, you won't play them.
