Hey.
Take the iBoook. I took mine on a 2 week missions trip to Peru in January. It was great. Had it for the plane rides, and was able to connect to email here and there during the trip. Also updated a blog for people back home that were following our tip.
Took lots of photos, and never had to worry about running out of space, as I would transfer images from camera to ibook periodically. (I have a 2GB card with my Canon SD550 7.1 Mpx)
Take it and enjoy it. You wont regret having it.
