Hello! This is my first post to the forums. I was reading some of the threads regarding people's thoughts about upgrading, and generally I agree with most posters. The current model is great, and if you need it, you should buy it without hesitation. However I saw this post and am intrigued to hear more thoughts: http://forums.macrumors.com/showpost.php?p=13328405&postcount=18 I have seen multiple posts in agreement on a couple points. a) The first models after a hardware redesign have either been replaced with a bug-fix model much sooner than the regular refresh cycle b) The first models bask mostly in the redesign, but the second model may get fixes/better hw in a short period of time. What are some thoughts and experiences on this?
