I don't understand why waiting has to be something that bothers you or takes your time. If you want to take a look at OS4 before deciding between it and MorphOS (or indeed, nothing), just forget about it until its out.
Theres a big world out there... go.. enjoy... be freeee!
If you take a look at AmigaOS 4 when it comes out (or, indeed, decide it sucks, but decide to give MorphOS a look), then you'll probably come back, and we'll all still be here. Hopefully by then, we'll all have stopped bitching at each other, too :-D
