Reviews on the Air are great, especially enjoyed the in depth detail of Anandtech.
That said, The fact that the Air is still limited to 1GB of RAM, means it is likely not as future proof as some of us would have hoped. I am one of the (apparently) few on here that loves iOS7, but I expect iOS8 and later will have more system requirements going forward, and I hope for the day when we have more Multitasking functionality in iOS than currently available. An iPad (for me) is a multi year device, and with iOS devices now being 64 BIT going forward, I can't see much longevity in a device that only has 1GB of RAM.
It is also frustrating that the base spec is still only 16gb. I personally feel that no tablet (talking Samsung, Apple, etc) has any business being sold with anything less than 64GB of storage. If they do insist on having a low entry price point, don't charge astronomical amounts of money for reasonable flash storage.
This is the first time I have ever felt such huge disappointment with an Apple release. And NO, I am not leaving Apple's fan base, I just don't intend to give them a sale this round. If I didn't have personal misgivings with Samsung (Nothing to do with the Apple v.s. Samsung History mind you), I would be considering a 10.1 .
