Hi folks. Just to give you a bit of a point of reference: -I have a current model 21.5 iMac -I have been using a 2010 13" Air with 2GB ram I guess I am looking for a bit of insight on a recent purchase of a 13" MacBook Pro. I was planning on getting a 2012 13" Air with upgraded RAM, but I had the opportunity to purchase an open box Mid 2012 base 13" Pro for $850 and I jumped at it. Now that I have had it for a few days, I cannot tell if I am crazy or what, but this new computer seems terribly slow. (I also do not know if it is because I have went from using an Air with and SSD to a Pro with a HDD) I mean like oddly slow (system preferences took 15 seconds to load, Keynote took 23 seconds), and I am getting a lot of bouncing icons on the dock. Is this because of the HDD spinning @5200 RPM? The 4 GB of ram? Or, Should I be more concerned? The laptop was originally purchased and out of the store for 2 days (I saw the original sales receipt) and was returned for a Windows PC. Could it be that I have a lemon? OR Should just focus my efforts on upgrading the RAM and getting a SSD? Do any of you experts out there think that this would help? Opinions are welcomed, and thank you.
