I have not yet seen this software but the announcement sounds interesting. For one thing, I am not used to seeing much genealogy software produced in Iceland. For another, the word "Osk" means wish in Icelandic. Here is an excerpt from the announcement of Osk version 4.0:
Studlar Software has updated Osk, a genealogy application for Mac OS X and Windows XP, to version 4.0. It’s a Universal Binary update, so runs natively on both PowerPC and Intel Macs.
Osk enables you to enter detailed information about family, friends and celebrities, with birthday, connected media, places of residence, sources for your information and other data. You can plot family trees and track ancestors and descendants. It’s available in English, Icelandic, German, Russian, Portuguese, Norwegian and Swedish.
Version 4.0 offers better overall performance, enhanced text reports, better Gedcom 5.5 import, and improved tracing of relatives. Osk allows you to keep track of your friends and family, celebrities or any family information. You can create family trees, export them as JPEG or PNG pictures, and then export your information as a web site.
Osk 4.0 runs on Mac OS X 10.3 and greater, and on Windows XP. It’s available as a fully functional 30-day time limited demo; registration is US$39.
