I am a long time windows user recently came across mac and was really impressed (quality, easy of use and sheer enjoyment of using). I am looking to updgrade my laptop so seriously considering switching to Mac. Was doing some research and came across this web site (www.xvsxp.com) that I think gives unbiased opinion. It compares OS x vs. XP and points out strengths and weakness of both systems. X scores higher than XP (724 vs.627) but people who are considering switching may want to take a look in terms of OS what is important to them. I have couple questions and will really appreciate feedback. 1. If Apple comes out with new powerbook in next few months will the price of existing powerbook go down?if it will then by how much? What is the historical trend? 2. Are there any issues using Office Mac? I am heavy user of Office and it is very important to me.
