Papyrus

From R.O.M. logicware:

Papyrus OFFICE incorporates a powerful word-processor with desktop publishing and integrated spreadsheet capabilities, with a relational database including an intuitive user interface for instant searches. Twelve years of development have given Papyrus a complete range of innovative features; nevertheless, we still focus on what is really important for our users. This is why Papyrus has become the fastest, most efficient, and probably the most stable office software package sold today. You can even use Papyrus from a USB memory stick. This means that you can take your Papyrus (and your data) with you, and use it on any Mac (or Windows) computer. Remove the memory stick, and leave the system untouched. Of course, you can also use Papyrus traditionally, installed on your hard disk: its your choice. (You can install your Papyrus onto any USB Memory stick simply by copying the installed Papyrus folder - less than 10 MB! - from your hard disk to the USB stick.)
