Hello! I am trying to decide if this is the right time for me to upgrade my Air... I was wondering when do you guys consider upgrading...besides wanting the fastest, the newest and the shiniest toy... How do you decide when to take the plunge??? I have a mid 2011 13 inch Air and thinking and wondering if I should/need/want to upgrade. There is nothing wrong with it... In fact, I still have close to 169GB available out of 250GB storage... My day to day use involves mostly internet browsing and email, besides holding my pics and music...it is sort of my main machine. I also have iMac from 2010 but hardly ever use it b/c its sitting in not main area...(also have ipad mini which is used for listening music purposes) (I might or might not be going back to finish my BA online...so I am not certain if I use iMac as possible display or not...I might...) Also, minor detail...I will be overseas for the next 3yrs and so I don't know if my current Air will be sufficient enough...(can't consider purchasing locally since the currency exchange will make it considerably higher price...) 2014 Airs...are they so much better than my 2011?? Will I notice the huge difference/improvement?? The question about the screen size, I am thinking of going to BB and see it myself. When I decided on my Air back in 2011, I felt that the screen on the 11 was too small...but I might consider it...since I started to think 13 is kind of big for me...(I make things small and have kind of wasted screen space) If you wouldn't mind sharing what triggered YOUR past purchases or any input, I'd be appreciative! Thank you for reading my post.
