I would actually say this is a better time than most.

Not only did they just do a really good update that makes the machines really cool and vastly improves graphical performance, any current purchase comes with a free upgrade to Mountain Lion when it drops (prolly tomorrow).

I snatched a 11" a couple weeks ago and it's one of the coolest toys I've ever owned. It's a deceptively powerful little thing. It could actually serve as a main computer for anyone who doesn't video game or do heavy video editing. It can run multiple external displays!
 
i got the 2011 model from last july..
I'm still very happy with mine and i can only look with jealous eyes on the people with the newer ivy bridge cpu (HD 4000). its a nice upgrade, graphically.

although this does exactly what its supposed to do. media-wise, it can easily run 720p videos on youtube, which is exactly the max i require from it, apart from a few indie-games like plants vs zombies and world of goo...

i don't know the performance difference, but i imagine its better on the newer one :)

overall its very fast, nice designed, comfortable keyboard, very nice screen and weighs... nothing.
 
Ordered mine last week. Getting it tomorrow :) This is the best time - you've just had an update, and the feedback on the update has been good. There are no critical flaws with the 2012 refresh - so you're all set.

Plus I don't think there's anything in the 13" rMBP rumours. Just a load of BS in my opinion. I don't see that happening for at least 1½ years, defs after Haswell.

You're fine with buying now :)
 
Yeah go for it. This year's update may not seem like much, but imo it's quite a big upgrade.

- Graphics card: HD 4000 is up to 60% faster than HD 3000.
- USB 3.0
- 720p FaceTime camera
- Better fans (I think?)
- Upgradeable to 8GB of RAM
- Ivy Bridge (a little faster and a little less power hungry as well, so the battery seems to also last a teeny bit longer)

MBA mid-2012 is a solid machine.

The SSD on my 2012 MBA easily benchmarks 2x+ faster than my 2011 MBA. Not that I had any problems with the speed of my 2011, but .. holy crap with the new one! :)

Right. How could I forget.. the SSD speeds are now 6 Gbps, as opposed to 3 Gbps (2011). :p

You forgot faster ssd.
Edit: too slow.
 
Buy Now :)

Now is a great time to buy an Air. I am upgrading from a Core2Due MacBook Air 13.3" (Late 2010) model. I will see drastic improvements in performance if the reviews and tests are to be believed. Real world experience with in-store units confirm the "snappyness" of the new units. They will be perfect for Mountain Lion.

Custom build times seem improved with my order arriving within 4-business days.

I started on a mid-2010 and the 2012 blows it away on every performance fronts.
