IMHO, it all depend on how you define "embedded". Our product is a huge
core router (www.hyperchip.com), the resources on that board probably exeeds
may high-end workstation and servers :-) . Yet we would condser that
"embedded". Rather than building our own SW facility over an optimized OS
(either RT or home-bru), we decided that having a *NIX OS was a "scalable"
thing to do.
Also the POSIX interface was existing INET source code was extremely useful
when time-to-market is considered.
The other issue to consider is SW licensing, IMO Linux is probably not good
for embedded product, using Linux may expose your company to "legal" issues.

I also agreed with you that Linux is on the road to bloat-ware. Back in 90s
I was able to run a minimal Linux efficiently on an x86 based 8meg of ram
and 2meg of flash for a small Telecom company in Virginia. However recently
I tried installing Linux on Pentium II 32 meg machine and it was painfully
slow. I think the recommended Minimal system for Red-Hat 8 is
Hard Disk Space*:
Minimum: 650MB
Recommended: 2.5GB
Full Installation: 4.5GB
*Additional space will be required for file storage.
Memory:
Minimum for text-mode: 64MB
Minimum for graphical: 128MB
Recommended for graphical: 192MB
=============
If that's not bloatware, I don't know what is :-)
