If I was you I'd give up on OS4. I doubt it will be out this year, at least not in any usable form. And if it comes out later than that, there won't be any users left to sell it to.
I gave it until the end of last year before giving up and selling my PPC Amiga 4000. Ben Hermans promised OS4 for CSPPC before the end of 2002, so I set that as my deadline.
AInc said CeBit will be the big relaunch of the Amiga desktop platform and OS4, but now it appears they havent even booked a stand...
AInc is dead in the water. They haven't got two pennies to rub together and no products to sell to generate revenue.
Stop waiting and start doing. Make a clean break - get yourself a nice Pegasos and MorphOS and start having fun again. It's real, its working, and people are using it right now.
Sure, some people will tell you to wait "just a few more weeks" and that Pegasos isn't a "real Amiga" and that MorphOS isn't AmigaOS. Well, if you want to wait forever just so you can have the "Amiga" name on your case then go ahead.
