    If you have 30 minutes to boot up, this is what you need.  What happened to recommended system requirements.  Minimum Requirements here and yes it may boot.  But recommended requirements at least got you running without waiting on a pot of coffee to brew.  I would always double the recommended and I could even run an app or two.  But this is laughable if you have any since of productivity.
