I'm getting a 21.5 iMac soon to replace my current home desktop. This thing is horrible, just starting up the computer and waiting for everything to load takes like 10 minutes. Anyways, I went to the Apple store today and checked everything out. I've been wanting a laptop as I am heading into my first semester of college this fall but I'll probably have to wait until christmas for that. I'm getting a 21.5 inch iMac soon but was wondering which model to get. I'm a big guy about graphics. I won't be playing any games on my new mac, but when I can see pixels or blurry details it really pops out. In the store I compared different models of computers, laptops and desktops alike. The highest end models definitely looked clearer than the lower end models. Should I get the lower end 21.5 model or the higher end 21.5 model? Will the extra speed and graphics processor even be noticeable? Also I plan on getting my MBP around christmas. I read a few topics and saw people talking about upgrading to high res screens. How do you do this? I see no options about this on the apple website, and knew nothing about this when I went to the apple store. Like I said earlier, I compared different models and could quickly see that the lower end models looked less vibrant and details looked very blurry. I can't stand that. Explain how to upgrade to high res screens and how much it costs. I have a Samsung Vibrant android phone and the screen on this thing is amazing, looks a lot better than the iPhone 4's retina display. I was sort of let down by how Apple hyped it up but my Samsungs super amoled screen looks noticeably better. I also play games on my PS3 on an HDTV so I notice small graphical details. Thanks for any advice! I can't wait to replace my current desktop. Also, what software do the iMacs come with? Will I have to pay extra for things like iMovie, or Microsoft Office?
