Last month our five year old iMac gave up and I started visiting several Mac forums to get info on just what you are concerned about: what will be the next new thing? I'd like to have a dollar for every sure thing rumor about new 20th anniversary Macs, Super Bowl Macs, etc., that were posted all over the net. Last weekend we purchased a new eMac and are glad we did. Got the superdrive, upped the memory to 512, threw in a Canon digital camera, all for less than the cost of an iMac. This wouldn't be the route to take for everyone but for our family it is great. At first the fan noise was more than I liked but after a few days I don't even notice it, especially when listening to iTunes! The only problem is that now we have to invest in better speakers, lenses and a watercase for the camera, a panther how to book,etc.. I really don't think you will be sorry if you get an eMac now but what do I know. Maybe a new one will be introduced right around the corner.....say, the next SuperBowl???
