Software Installs

Hi,
After doing a lot of reading on the BCN web site and this forum, I decided to join.

I'm thinking of purchasing both the PC and PDA version of the software.

I have two questions:
1.)  Can I install the PC version on more than on PC, i.e., PC (for home) & laptop (for travel);

2.) Can I install the PDA version on both my wife's and my  PDA?

Thanks
