Id have to contend. Paul Smedley is working on Gnash (open source Flash) as a stand alone player and a plugin for Firefox family of products, so no need for flash player there.
Realplayer is okay, however, WarpVision plays most formats of audio and video, and PM123 could have a plugin written for it to play your real-audio files. This sort of negates these programs as needed to be run through Odin. Of course, there are probably other features/reasons you wish to have these applications through odin, so I can not say for sure.
I think the Odin API should be a complete solution akin to WINE so people have the ability to run whatever they wish. This is an incredibly attractive feature of a non-MS operating system for those people who have a pole up their ass about using Windows for whatever reason, but still wish to use Windows software. Myself, I dont mind windows, and I want Win32API support for eCS because its cool and I like working in eCS. Id also like to see eCS/OS2 stay alive, and if it can keep up with the Linuxes a little better, this will become more of a reality.
Myself, I feel that Microsoft Office can not be without. OpenOffice is okay for free software, but I am paying a subscription to it and it, im my opinion, is not worth any ammount of money.
