I need a little (a lot) of help deciding which of these to go with. Let me first say I hate windows and PC and love my mac. But if I want to use my mac for work I will need windows to run from time to time. I need to be able to run IE and some window's based work software and really thats about it. Everything else I can do on the mac side. Given those simple things which of these would be the best to let me run windows? A few other things that are important to me, are start up time, battery life and program loading time. Small things for sure but which ever route I go I don't want it to slow down or kill any of those small things or anything that I have become used to with my mac and it's OS. Let me know if you need more information. Thanks in advance.
