No, I don't think it would be.  From experience with the MC68EZ328 
processor, that was slow, but was workable.  The EZ328 was clocking at 
16MHz, I would expect that the ARM7TDMI-S would be quite snappy!

It all depends on your point of reference, if you are comparing against 
a Pentium-II or Pentium-3 processor, yes, it would be comparatively "dog 
slow".  However, if you are an embedded engineer and have been around 
microprocessors for many years, the ARM7TDMI-S @ 60MHz running uClinux 
would be sheer joy!
