I have a perfectly good PowerPC iMac at work that does all I need it to do including being in my MobileMe sync mix of devices: iPhone4, iPad1, Mac Pro (Snow Leopard). I hate the thought of having to get rid of my PPC iMac just so I can get a new computer that can run Lion, just so I can keep my work computer in the calendar and contacts databases sync loop. And of course if I get a later model computer for work, some of my apps will need to be upgraded too, like Word and Adobe Creative Suite which is EXPENSIVE. Seems such a waste to force me into a computer purchase just to have it run Lion just so I can have it communicate with iCloud. Anyone know if there's a workaround or 3rd party app that will allow a PPC on Leopard communicate with iCloud yet?
