All macs have USB & Firewire, any digital camera will use one of those, pretty much every camera out there you simply plug in and it works, no software needed. Most of the Apple laptops come with wireless cards now, if not they can be purchased with it, the signal strength is pretty damn good, particularly on the iBooks as it's intergrated into the display. iPod is firewire so iBook or PB are fine. A 12" iBook is plenty fast for normal stuff, decked out with 768Mb RAM and an 80GB HDD (wireless built in) it's roughly $1300. Can dual-boot linux too
