Hi, I have limited desk space and am currently using a PB Al 15" perching on an iCurve with external keyboard and mouse. I am thinking about getting an external display and here are two options I am entertaining: 1). purchase a 20" cinema display and use the PB in clamshell mode placed under the display, or 2). purchase a 17" studio display and use the PB in spanning mode with the iCurve next to the display. Option 2 is obviously much cheaper, but will lack the elegance of Option 1. Any thoughts or advice? Thanks.
