All,

A few quick responses to key points that I feel need addressing.

Many of us do. Nothing wrong in stating this. Apple has built an incredible 
religious following, both with the OS and architecture. One of my employees 
wrote in to our team list and declared he was 'going to be drinking the rest 
of the day', don't bother trying to get ahold of him :)

The Power Architecture family encompasses POWER, 970, and Cell. The 970 
already exists in a deskside tower and 1U rackmount (outside of Apple's 
product line). Some immediately available, some in motion to be soon 
delivered, some on the drawing boards. But by the time your current systems 
are ready for replacement, you'll have options.

The 970 is immediately capable of being implemented in a laptop (the 
power/performance curve drops off quickly), but of course at a slower clock 
speed than the desktops. The market perception of clock speed has most likely 
kept the 970 from laptops thus far.

Most everyone is looking at what IBM supposedly did _to_ Apple and how Apple 
responded. Is it possible that this is really about what Intel _offered_ 
Apple and what Apple did to IBM? What color of money would drive you to 
knowing kill your own hardware sales for a year in order to make this switch? 
Think about it ....

The Power Architecture has an enormous installed base (mostly DOD at this 
point) with 970 growing. Cell is taking hold rapidly (faster than 970 did) 
with OEMs and holds an incredible potential (more below).

Not impossible: 220GF / 8 SPEs = ~27GF per SPE. Not unlike the current, single 
core 970. I viewed a Cell proto at POWER.org this week (in a BladeCenter 
form-factor) running Fedora3. Relatively non-invasive kernel patch. A thin 
SPE MPI implementation already exists. 8 "nodes" on a single chip. It's real.

The 10 o'clock news showcases the murders each night in a given city. But if 
they showcased all the births or weddings, it would be a 3 hour program. Just 
because the news reports what IBM is supposedly not doing, from one point of 
view, does not mean this is the whole story.

Understand that I love/hate Apple as much as anyone, but keeping a slight 
distance from the whole thing is important. The picture is clearer a few 
steps back.

970 is _not_ dead. Not by a long-shot. IBM has a large investment in this 
technology and is moving ahead with its own products and those of OEMs (see 
previous mention of this).
