My wife and I are new to Macs. We just bought a Mac desktop and Macbook Pro laptop, both with Leopard. We are going to network them with an Airport Extreme. I want to transfer my old PC (with Windows XP) to the Mac desktop, primarily so I can run Quicken and Microsoft Access. My question is whether my wife could run those programs through the network from her Macbook Pro laptop without having Parallels installed on that laptop? If not, how best could we transfer the old PC to both new Macs?
