I have to say after all these years in building regular size computers that I thought I couldn't be surprised any more. I was wrong for the Raspberry Pi and Raspberry Pi Camera has surprise me with how easy it is to set up, use and configure. I'm also starting to learn a little bit of linux in the process that is an additional benefit and understanding how a computer really works. I'm one step further in reaching my goal of setting up a camera that will monitor my bird feeder.
I just want to add something else that was in another thread, if you have an older PI just don't boot to the gui just boot to the command line. Though I bought the latest Raspberry Pi and using the GUI is nice, it isn't that necessary to do so. This should resolve your slowness issue and if I ever get bored I might just try that with my old Raspberry Pi, but for right now I working in finishing my project.
