[OS X TeX] Problem with cocoAspell in Tiger

My experiences with Tiger are quite the opposite and I wouldn't like  
to miss it. My general impression is that the System software (memory  
management, repairing permissions, copying, etc.,....), Safari,  
Preview and of course TeXShop are running much smoother and faster -  
in the case of Preview and TS this is certainly due to PDFKit.  
Running pdflatex, including the displaying of the pdf file, or  
Flashmode, e.g., is much faster.

Since I am no expert I can only speculate what could have caused  
Bruno's opposite impression, but it might be due to the different  
CPUs: Maybe one will need a G5, or even one with 2 CPUs, to take  
advantage of Tiger.

Let me also add, since Bruno mentioned his PowerBook and many members  
of this list also seem to be proud owners of a PowerBook, that a  
PowerBook is certainly a nice computer, but it is not supposed to be  
a substitute for a real workstation, it is only meant to be a mobile
