Most of the notebooks don’t come with numeric keypad. What you can do now is turn your iPhone or iPod Touch into the numeric keypad for your notebook, the NumberKey Connect app. There are four colors to choose from, they are the Black, White Silver,and Classic. It is compatible with iPhone or iPod touch with software version 2.1 or later. It says in the description that “this app is only available for Mac only at this moment”, but I saw there’s Download button there for NumberKey Connect1.1 (Power PC Support).
