Hi I am considering upgrading my first gen MBP to either: 2.4 Aluminum MBP or last rev of the MBP That is about equal cost, actually a little less for the MBP online. Here is what I like and dislike about my MBP. - The heat, way too much, hate not being able to use it in my lap and to hear the fans come on with the help of SMC fan control. + Screen and keyboard is great. Would like to use 4 GB so I can run Vista in WMware. Dont really care about express port, never used it. Have an imac with firewire so that doesnt matter either. Want something fast, cool, portable, great battery time, backlit keyboard and 4GB Want a good screen but 15" not a requirement. I read a lot of good about the lack of heat in the MB but bad screen while the previous MBP has great screen but seems to suffer from heat problem still. What is the advice, MB or MBP previous generation? Many thanks in advance!
