Wrong, wrong wrong. How many times do you use comdlg32.dll? gdi.exe user.exe
After a number of passes the Crusoe architecture will run these faster
as it profiles the code and optimises it.

Well actually you are. The same piece of code gets run each time you
pull down a menu/access the hard drive. These benchmarks are
fundamentally broken in they assume the result is identical between
runs.

Explain why a crusoe can happily decode DVD in software. No 250Mhz celeron
can do that.

HP pioneered the research that made Crusoe possible. They ran software
on an emulator that emulated the processor it was run on, and it
was faster than running natively. Why? Because it could analyse the
code and optimise on the fly.
The HP software (Dynamo) is discussed at Ars Technica

This sort of stuff is gonna be huge, and the PC press (as usual)
are too clueless to realise what it means. Hence their benchmarks
are useless.
