Ah..the age old question..PC or Mac..the battle continues. To be honest these days it does not matter whether you use a PC or Mac. You can get excellent results with either a PC or a Mac. Some things you should watch out for on either platform though are the following..

PC - 2Ghz Minimum - CPU - 2Gb RAM - 500Mb free disk space

     - USB and or A Firewire connection

MAC - 2Gb RAM - 500Mb free disk space - normally Firewire connections are preferred on Mac.

Whichever platform you use make sure you select the right stop motion software for you..more on this in the next section.
