You may be able to get iBooks from the App Store but I would be very careful to ensure it works under your current operating system. Otherwise, go for the Kindle version. Alternatively, buy a new super-duper Mac. That is what I did after my old one start to go on the blink after 5 years of intensive use. Edit: looks fully illustrated. I have a 2011 Core i5 iMac - that's pretty super-duper! Unfortunately, I'd have to abandon Photoshop (CS2 - one of my 'killer' apps) if I had anything later than Snow Leopard, as it needs Rosetta in order to run. Yep .. that is one of the problems with Macs. That said, on my 2008 Mac (the one I just replaced), I started with Leopard, and upgraded through Lion. My new machine has Maverick but I had no problem loading Photoshop Elements (v 10.0) from my old machine onto the new one. CS2 does appear to be available for later Macs so that might be worth looking at.
