I have concluded that my office is in sore need of a new display and have decided to take the hit for one of apple's refurbished displays. The most important thing for me is similar pixels/square inch (so that the same size font shows up the same size on each monitor). Is there a screen-definition difference between the most recent MacBook Pros and any of the currently available cinema displays on Apple's site? I could not find any such specs in the product descriptions.
Using this calculator, I discovered that the following:
24" cinema display has 94 PPI
Thus the 27" is going to be the closest PPI to my current display.
