Performance
The Ivy Bridge equipped MacBook Airs are definitely faster than their predecessors. But if you're like many and are upgrading from a 2010 or earlier MacBook Air, the difference is astounding.
The improvements don't come exclusively from the faster CPUs, but also from the significantly faster storage. For the first time since it started using SSDs, Apple is at the forefront of solid state storage and the impact on performance shows.
The new Air boasts faster boot time than even the rMBP, I can only assume due to a simpler hardware configuration that allows for faster initialization.
There's a minimal performance difference between the 1.7GHz and 1.8GHz CPUs, but the upgraded 2.0GHz part offers a tangible increase in performance - especially in our CPU bound video transcoding tests. The upgrade is worthwhile if you're a power user trying to make an Air work rather than taking the portability penalty and going with a Pro.
The MBA as a Desktop
With Ivy Bridge, using the MacBook Air as a desktop replacement is surprisingly possible. UI performance on an external Thunderbolt Display at 2560 x 1440 is indiscernible from the rMBP with only a few windows open. It's when you start opening a ton of applications and browser tabs that UI frame rates slow down appreciably. I clocked scrolling down an AT review at 30 frames per second, and activating Exposé with 17 windows open rendered at 18 - 20 fps.
Application responsiveness is quite good thanks to the incredibly quick SSD. With last year's MacBook Air it was possible to have one of these machines serve as your older MacBook Pro replacement. The improvement in storage performance and 8GB memory offering really seal the deal for this year's model. There's still an advantage to going Pro as you've seen in the performance tests thus far, but if you don't do a ton of heavily threaded CPU work (e.g. video/photo editing, 3D rendering) then the Air really can cut it as a primary system.

Wow, superb on the UX32, Anand! Just what I was in the market for. Bonus points if you can run the Photoshop speed test in your review (perty please).I'm currently looking at this beauty to be my desktop replacement (for photo retouching) soon hopefully with a swapped out SSD instead of the hybrid drive and upgraded RAM.

"Similar to the rMBP, the actual power adapters themselves haven't changed: 45W is all you need for both systems. "Nice. My new Ivy Bridge Dell requires a 130W adapter, and gives me an error message and runs at reduced speed with a 90W adapter. These same adapters worked fine on my older, supposedly more power hungry, 17" laptop. Lame.

Well, it depends on the philosophy of how they design the power adapter. My dell actually has a 180W power adapter, but there's a good reason for it. They designed it for the worst case, where you have to charge the battery at 50W, have full GPU+CPU load, HDD load, burning a DVD, full brightness, and while charging multiple devices. On the other hand, I can't imagine apple's power adapter could handle full charging speed while charging an iPad and handling cpu intensive tasks.KPOM - Tuesday, July 17, 2012 - link
It's partly this "just in case" thinking that can slow progress, particularly in the Windows world. My employer has HP Elitebooks as late as 2011, and they still include VGA and modem ports "just in case" they are needed. VGA I can almost see, but modems?Pessimism - Tuesday, July 31, 2012 - link
VGA: Eleventy five billion legacy digital projectors in schools and businesses (case in point: my workplace is just now upgrading from a fully working 10+ year old 1024x768 projector that has a VGA input and no digital inputs)Modems: Dial-up internet and PC Faxing transmissions from hotels in third-world countries. Yes, there are business people obsessive enough with their jobs that these two functions are mission-critical to them.
All it takes are a few LARGE, corporate customers who lease or purchase these laptops by the thousands of units to keep such legacy ports in-place. Someone using an Apple product would need a bag full of $49-99 dongles along with their svelte macbook to replicate this functionality.

You can buy a larger power supply if you like. Apple sells both 65W and 85W MagSafe(2) power supplies. But of course they are larger. Most people prefer a smaller power supply for traveling.It's silly to complain that Apple is not serving your very particular needs when they are probably matching most people's needs optimally, and when they DO provide an alternative for your very particular needs.

I've just recently switched from my late 2008 15" MacBook Pro to the 2012 13" MacBook Air. I needed the discrete graphic card when I was still on duty onboard ship but now that I am at university that tradeoff was just to cumbersome, so I decided to purchase the new MacBook Air, as my university participates on the Apple on Campus project and the back to school event is just on. I was really not sure if I should go with the 13" or the 11", but the deciding factor was the battery. Turns out, with my light working load at university (just Word and Preview with some pdf open), screen brightness to 50%, backlight from the keyboard off, airport off I actually get around 10 hours of battery life, which is completely nuts compared to the 3 hours I got on my old MacBook Pro with the screen on lowest brightness setting. I have to add though that I manually set the time for the hard disk to power off to 3 minutes via Terminal (10 min are standard by Apple).Next years Haswell should bring further energy saving increases, hence allowing me to get the 11" with comparable battery life. On top of that maybe some of my games I played on the MacBook Pro 15" might be possible to run (Civilization 5, Deus Ex, Skyrim). Looks to be an exciting time in roughly 1 year ;-)

I've seen skyrim play manageably on an Atom + Ion netbook, so this should be fine.mastertoller - Monday, July 16, 2012 - link

Hi Galatain,Impressive battery life you're getting. Out of interest, is it the i5 or i7 you have?
Cheers
