Will software run on both the BeOS for Intel and BeOS for PowerPC? Or will I need different versions?

That being said, given how easy it will be to port BeOS software from one processor to another, it will be very easy for software developers to include both versions on the same CD, or allow you to download both versions at the time of electronic purchase.

In fact, while there are no "fat binaries" for the BeOS, most commercial software now comes in "fat packages," meaning the installation package includes the software for both platforms, and will install the correct one on your system.
