All I care to do on my laptop is MS Office, Photoshop, Lightroom, Indesign, Illustrator, and Dreamweaver. Ah, and internet so I can access TPF of course. Recently I have found several laptop deals that have 4GB RAM, a 64-bit OS, and large hard disks. This all sounds very lucrative. Does anyone know how Photoshop runs in a 64-bit environment?
