Well, Intel wasn't exactly in the "mood" to "license" at first.  But
they did license it -- although I don't think the first chip had it, it
wasn't until the WinChip2?

The IDT WinChip was an interesting design.  It did not have out-of-order
execution and a few other details.  They built it with a minimum logic
set, so it took little time to go from first design to end-user silicon
(only 18 months), put a huge-@$$ cache on the sucker (64KB L1 was it? 
which was unheard of at the time), and it ran at 3.3V so it would work
in just about any mainboard.

The follow-up WinChip2, 3 and ended with 4 before they got bought out by
ViA.

Largely because they were the first to release a Socket-7 processor and
Intel wasn't licensing at the time if I remember correctly.

WinModems easily need 50-100MIPS -- so there's half your CPU now busy.

Engineering and marketing _rarely_ agree.  Otherwise Intel would stop
farting around with SSE and build some seriously powerful chips.  I know
several Intel engineers (and former engineers) personally.

Normal with Windows???  I've been running Linux on my Toshiba 2805-S402
for over a year now.  P3-850, nVidia GoMobile 16MB, DVD/CDRW, 256MB RAM,
20GB HD.  I should have waited a few months and gotten the ones with
more memory and disk, but I wanted the first notebook with an nVidia
GoMobile.  Awesome Linux OpenGL performance!
