doesn't have native threads right, so not much point in having all

possible because everything is going multi-core.

I seriously doubt that the best way to make use of all those Cell processing units is with any kind of threading. I expect there's probably some way to more tightly synchronize their actions, when coding hand assembly. I'm not interested in the Cell as some kind of architecture where you just forget about what you're doing, put stuff in threads, and hope they perform better. That's how the XBox 360 is designed; its threading model is coarse and conventional. I'm sure it will be popular with developers that don't want to think much about the architecture. I expect, however, that the Cell has capabilities that can only be realized by writing very specifically for that architecture. I haven't read up on the Cell enough to know what is possible, but I will be doing so.

As a console it seems to be bombing so far; they are already going for
less than retail on ebay,

Um, no. They've been going for $1500 on e-bay. That's 2.5 times their $600 retail, and almost 2 times their $800 manufacturing cost. Sony was supposed to deliver 400k units at launch and has only done about 200k. Crimes have been committed by people to obtain them, including murder.

Besides, the Cell isn't going to be used in just the PS3. That's just the cheap way to get ahold of one right now.

and Christmas isn't even here yet.  With any
luck, after Christmas they will just keep getting cheaper.

Yep, that I do hope.
