My girlfriend has a situation here. She's a design student that wants to buy a Mac. She is deciding whether to buy a 15" 1.33Ghz powerbook or a powermac dual 1.8Ghz. The price difference between the two is $100(CDN) more for a powermac. She's leaning towards getting the powerbook because she has a PC she got not too long ago and she wants to continue using that for various reasons. I personally think it's better for her to get the powermac because it's more powerful and will be great for her to do her design work on. If she were to get the powermac, would there be a way for her to hook up the powermac and a PC to one monitor? Her monitor is a Samsung SyncMaster 171s. Any advice on this is much appreciated, thank you.
