I don't want it to fail, but I don't expect it to do otherwise and won't be shedding any tears if it does. If the actual retail price is anywhere even approaching the figures they were quoting, I have a hard time seeing how they'll sell enough units to keep things going beyond an initial production run (unless the vast majority of that is markup, in which case I would want them to fail, just out of spite.)
But I'm really not invested one way or the other - PPC hardware and software bores me and I have no interest in OS4, so I'll just keep waiting for NatAmi and praying that it will have a price tag somewhat less than "one semester at a small college."
