I still haven't experienced what it's like to hook my iBook up to an external monitor but since I have recently ordered a Dell 2005FPW I figure it's time for me to ask a few questions to prepare for it's arrival. How is the performance overall when mirroring? How about the performance when you enable screen spanning (using the hack, of course)? Do things get choppy? Will I notice speed problems if I start watching DVDs? Do the iBooks heat up a lot when mirroring or screen spanning? Does that mean that my fans will constantly be on? I've heard many complaints about Expose and Dashboard. Does that mean that both of these services are pretty much useless when using an external display? Oh, and my iBook's specs are in my signature. Thanks in advance.
