I'm planning on getting a PowerMac but have been a bit hesitant. I've been watching the rumors for about a month, but it seems we won't see Rev. C PowerMacs until WWDC.. However, I need a new computer now, and therefore have been eyeing up the Mac mini for a temp. machine. I'd be using this for a few months for Photoshopping, email, the internet, iLifing, etc for a few months. after that it'll just be an email/internet machine for light word processing stuff. Would the Mac mini be suitable for this? I was reminded by someone about the iBooks? What about them? Are the iBooks the exact same as the Mini, just in a portable form? Or should I just get the PowerMac now? I'd have to buy Tiger later on then too. Help.
