Digital BW, The Print

Hi all:

Please forgive me for asking this, but my existing PC is now filled 
to overflowing with b&w photo files, and it's time to replace it.  If 
you like, feel free to respond off-list, but please tell me if there 
is any reason why I should not replace that PC with a MAC.  (My 
reasons for wanting to do so include the huge virtual memory 
available and the beautiful flat displays.)  If it makes any 
difference, I use a Nikon 4000 scanner, Photoshop, and print to a 
1280 through the Piezo plug-in.  

Thank you.

Chuck
