I've wanted a new MBA since 2010 when the 11" came out...I have a whitebook that's in my signature and an HP DM4 = both have SSD's in them so they are pretty fast but at 5 lbs or 4.2 lbs respectively, they are an annoyance when traveling on business.
I also have an original iPad and a "new" iPad = both were/are great devices for the time they were/are introduced...but sometimes they just feel like "I can't do enough" on them...I also have camera connection kits, keyboard cases, stand alone keyboards, etc...so they are "well equipped.
...I still want an 11" MBA but with having all my above gear, I'm waiting for the 2013/2014 models to see what Haswell or later Intel road maps will bring to the table as I have no "real" need right now!
