There have been several threads recently about waiting to buy until the new iMacs are released. While I agree that it probably makes sense to wait, there are a few other factors that new buyers should consider. Do you have any legacy programs that won't run on Lion? The current iMacs can run either Lion or Snow Leopard. The new iMacs will be Lion only. Have you tried Lion? I am still on the fence whether I like it or not. Maybe it will grow on me, but I'm glad I have the option to switch back. Do you need an optical disc drive? We don't know yet if Apple will remove the drive, but if they do, that would be a deal breaker for me. As part of my business, I create DVDs for my customers everyday. Now if Apple adds a Blu-ray drive, sign me up for the new iMac!
