I'm a long time reader and a first time poster. I need a new laptop as my old 2008 MacBook white (lasted me 6 years)has gotten really really slow and freezes every time more than one program is open. I wanted to get a 13-inch MBP Haswell (non-retina) once it's released but I am now considering an MBA. How great is the difference between the MBP and MBA for non power users? And how long is the life expectancy? Below is what I will need the laptop for: Downloading movies and TV shows Internet browsing Writing papers and heavy email use Converting videos Watching movies Downloading eBooks and using Calibre What is the performance of the new Haswell MBA's even though they are still dual core? Can I add external storage? Does it freeze when multi-tasking?
