This is a question that is as old as computing itself!

But!

Why pay?

There are three good reasons why you should pay for shareware:

• It gives you a nice warm feeling inside to know you have done something good.
• You are helping to support (and therefore encourage) the army of shareware authors that have helped make the Mac what it is today.
• Shareware is generally cheap, hopefully it works, and solves particularly niche problems that the 'big boys' may not be interested in.

Why pay for Power on X?

• Power on X is a native Cocoa application specifically developed for Mac OS X.
• Purchasing a licence key will stop the annoying snag screen when you start the application.

What do I get for my money?

• A nice warm felling for supporting shareware development.
• The ability to use Power on X without a delay for the nag screen to clear.
• Access to table generation (useful for confirming the accuracy of Power on X by comparing with published power tables)
