In a year or so, Pentium will cost what the 486 costs now ($400?). The Alpha
is less likely to decrease in price as much. In any case, I agree that CPU
cost is pretty much irrelevant. I do believe, however, that Pentium will
win big in terms of total system cost, though.

Oh come on. Isn't that what they said about the 286, the 386, *and* the 486?

Can't touch the Alpha? I'm not so sure. The slowest Alpha machine in
existence runs at what, 150MHz? I find the fact that a Pentium running
at 1/3 the MHz of the Alpha comes within 15% of its performance pretty
impressive. And Pentium machines will simply blow away Suns and other
workstations in terms of price/performance. Even 486 machines are about
as fast as SuperSPARCs, and yet I'm sure you're not so critical of that
architecture.

Yeah, yeah. Intel bashers have been carrying this tune since the '70's,
yet Intel has managed to close the PC-workstation CPU performance gap
with that x86 architecture.

Hey, don't get me wrong -- I believe that the Alpha is an innovative
architecture, and will probably be more easily scalable than the x86.
Maybe I've just been turned off by the sh*tty system software that currently
runs on the Alpha and HP (and I doubt that NT will change my mind about that).
I don't want to sound like an evangelist, but IMHO, Linux simply wipes the
floor with both OSF/1 and HP-(S)UX, as well as almost everything else I've
worked with. SunOS/Solaris is the only OS that's in the same league as far
as I'm concerned. The thing is, I don't think any of this will change until
the hardware vendors stop thinking they can develop operating systems as
well. That's why my next machine will probably be a Pentium -- so that I
can keep running Linux/GNU/XFree86.
