I am currently running on an Apple Powerbook laptop and suffice to say it can hardly handle heavy post processing. I have come to decide that I will be buying a PC solely for the purpose of image editing (and maybe listening to music and watch DVDs). Now, I want to keep all my photos in a physical (no Flikr or the likes) remote location separate from the computeres but to which both the PC and my laptop can get access. I have no idea how this would work. Purpose an external HDD that's connected to the home network? Does such thing exist? What are my options? Thank you for your time!
