i just bought the NEW macbook air today, its the cats gonads
heres my review:
Working off formerly a 13" macbook air mid 2011, I just bought this new 2013 model with the Haswell CPU and low power consumption infrastructure.
Off a full charge, I disconnected 3 hours 40 mins and had an external drive connected the entire time, restarted 4 times, and did NONSTOP heavy application installs (Office suite, Photoshop etc.), a total of 23 applications, and ran youtube vids in the background the entire time, and after all of that nonstop heavy loading, I had 76% on my battery, of which id have around 35% on my older Macbook Air.
Further still, the entire unit has run UTTERLY COOL during this EXTREMELY heavy loading, installing and heavy 1080P video graphics play. My other Macbook Air would be almost too hot to touch underneath near back under same conditions.
Even without 802ac (new Wifi connection thru the new Air), I notice roughly 25% faster throughput on likewise file downloads using my new Macbook Air than that of my older version airport extreme.
My Macbook Air has been without a question my most treasured gem of "go-to" Mac product hands down, I own all of them (2 Airs, Macbook Pro, MacMini etc),...I was skeptical when I shelled out $1099 today for the new Haswell Air and its presumed prognosticated "crazy long" battery life and improved speeds overall; but the hype isn't hype, its real and amazing. The mere NOTION that I can overload this Air with App installs, and have a 2.5" HD attached for nearly 4 hours, run 1080P Youtube vids,...and still be at 76% Batt life is just, well, its stunning.
Tested out the NEW dual (stereo) mic and it IS much nicer in record, additionally the camera/vid is much sharper and crisper than my other Mac Air. Considering the price point is lower on these new Airs than the older ones, I give the new Macbook Airs a "110%". Having repaired laptops (non mac) in the past, and owned at least 20X more laptops than most consumers, I don't lightly conclude this is the cornerstone workhorse for everything I dare consider doing, fast got faster, and battery life now is enough to make a crusty "hates everything" person like myself nearly cry with joy. Congrats Apple! Homerun on this lovely gem.
This new Macbook Air brings TRUE definition to "disconnected" and "portable" to those who want to do a LOT of work free of power socket! Genuine portable is finally here, ...no more staring at the battery % to rush to shut down!
