Few comments.
Pagestream is a good page layout program in the same way word is a good word processor. Word is bad at page layout and pagestream is bad at word processing. Don't get me wrong, I love PageStream and I'm excited to see they are still kicking given all the market conditions that exsist today. Hell at Amiwest I bought two copies!
I'm glad to see they are moving forward with support for OS 4, if they want the money little early of all the companies I think grasshopper has proven them selves trust worthy enought to give them the 40 bucks.
For MOS, wait your turn

I'm sure if Grasshopper feels the 68k amiga version is not sufficient for that platform and they feel the market is large enough I'm 100% sure they will make a MOS native version. Till then MOS users, Amiga 68k and Amiga OS 4 users will all have access to the same feature set in 4.1, so no worries.
As for "beta" software, and working for the 5th largest pure software company in the world I know what I'm talking about, there are many different ways to handle a beta and lots of factors in choosing which way to do it. MOS has chosen an open beta for the Pegasos platform, seaming closed beta for CSPPC/Blizzard users (has .4 been released? I don't know). OS 4 is in a closed beta. One example of why this might be is supporting beta customers, another thing I know lots about. Support costs money and time. If you have a handful of developers working for little money and not much time (most OS 4 developers have day jobs) you don't want to hinder development with hundreds of issues from hundreds of differnet people, to setup a buffer between developers and customers, call it Support, costs money. The closed beta allows Hyperion to control the amount feedback and to control costs which is very important at this time.
So my 2 cents on "beta", OS 4 is beta, MOS is beta. MOS is public beta and OS 4 is closed beta. Simple as that.
