Ok, so me and my mom are both looking at getting iMacs this semester so we have great reliable computers to last us both through college. Now, I currently have a Macbook Air 2011 128 gig SSD. Theres nothing wrong with the machine but I have decided that I do need a "home computer" to last me a good few years. My mom is also fed with windows and my macbook has converted her to only using apple computers now, so much that she has started using her iPad 1 for a laptop. The way my moms desk is built does not allow for the 27 inch iMac. So she has decided to go with the upper end 21.5 inch. I told her about the new iMacs coming out in a few months and that she might want to wait for them. She said she doesn't want to wait if they are not coming out till the end of the semester. Can anybody give me a rough estimate of when we think the new iMacs are coming out. Also, she wants it to last her around 5-7 years. Now, ME on the other hand, I can wait. That said do you think I should go with the base 27 inch or the upper end 21 inch. I don't really do a whole lot to warrant the extra screen size but it wouldn't be a bad thing either. I want this iMac to last me a good 5 years or so.
