My family has been using a Macbook Air since it was first released (original and early 2011). It's about time for another update but from everything I'm seeing it doesn't appear that the updates in June will update the Air to retina. We love the Air for how lightweight it is as it gets carried around by all of us (including my 4.5 year old) and is the definition of a portable computer. I really like the idea though of the retina screens in the laptop as I have a hard time using my original iPad after I got a retina one. I see the 13" rMBP is 3.57lbs vs. 2.96 for the 13" Air. For people who switched from an Air to a MBP could you please let me know your thoughts particularly with respect to the added weight? Do you find it more of a pain to carry it around from one room to another or do you not even think about it? Does the extra 20% in weight or .6lbs seem very noticeable? Any other thoughts? If we're surprised and the Air is released with a retina screen I'll definitely go that route but it just doesn't seem likely. Thanks for the help.
