[Leica] What is Rosetta

The software for the Minolta is outdated; that's a given and it will never 
be updated again, so I have to bite that bullet. 

But here's the weird thing: the Epson flatbed driver is the very recent and 
is written for intel macs, and is supposed to good well into Leopard having 
come out just this spring. Still wants Rosetta.

Rosetta is a layer of software that allows older binary (executable)
files compiled for Power-PC CPUs to run on the newer Intel x86 CPUs in
OSX.  My guess is that your scanner twain plug-ins are not compiled
for x86 CPUs so in order for them to work, you have to run photoshop
in rosetta.

The downside is likely a performance hit because the older binary
format is being translated to run on an x86 CPU

I would try looking for updated twain drivers/plugins for your
scanners if you're noticing  significant performance problems, or if
photoshop is crashing or broken in some way.
