Hi. I need some advice about upgrading/changing my computers. I current have an iMac 20" (the latest white iMac model before the aluminum ones) and I also have a MacBook 13". iMac: 2.16GHz Intel Core 2 Duo 250GB hard drive 1GB RAM 20" screen Purchased: May 2007 MacBook: 1.83GHz Intel Core 2 Duo 60GB hard drive 512MB RAM 13" screen Purchased: January 2007 My iMac is my main computer which I use every day. My MacBook, however, is just my backup computer which I use only when I need a computer outside of home or when I'm on vacations, which is very rarely. I use it like once a week max to use it around the house with WiFi. Ever since I bought my iMac, it has this lagging/pausing problem, which I read on Apple's forums that many users are experiencing, even with the aluminum iMacs. I must say that my old iMac G5 was a lot better than the Intel one. My MacBook runs a lot better than my iMac but I just don't use really use it because the hard drive is too small for my needs. All I'm really looking for in a computer is that it is fast and responds instantly to my commands. I always have Mail, Safari, iTunes, and MSN open. But I often use programs like iPhoto, Pages, and LimeWire and they are quite laggy on my iMac. So I was thinking of maybe selling both computers to get enough money for a refurbished 17" MacBook Pro and get at least 2GB of RAM. I'm considering this since I find it pointless for my MacBook to just sit on my desk and be barely used and keeping files in sync between both computers is a hassle too. Do you think this is a good idea? Or is there a better solution out there for me? Thanks for your help.
