Currently, I have an Imac from 2006. 17 inch, 2.0 ghz intel core 2 duo, 1 gb of ram. I need a new mac soon. The one I'm using now keeps crashing, freezing and is just being a pain. Now, my question. Should I invest in a new MCB now? Or wait for the new update? Any word on when that will happen? That being said, I may want to just get the new Imac, but I'm just not sure. Any help would be great. Thanks!
