yes, I ran it before on a netbook while im out in the field, you would struggle with never ones, you will need atleast 2gb of ram otherwise rendering will take ages and may time out
The only limitation I have found - it will not run on Windows 7 or newer operating systems. I found out the hard way - spent $2,000 on CS2, and after the upgrade to Windows 7, Adobe said, "Give me another $1,000 to upgrade to CS4".
