Steve Jobs introduced the first MacBook Air during a speech at his keynote at the 2008 Macworld conference held on January 15, 2008. The first-generation MacBook Air was a 13.3"-only model, initially promoted as the world's thinnest notebook (1.94cm MacBook may be compared with 1.98cm for a previous record model, 2005's Toshiba Portege R200). It featured a custom Intel Merom CPU and Intel GMA graphics. In late 2008, the CPU was updated to a faster, non-custom Penryn CPU and integrated Nvidia GeForce graphics while the hard drive capacity was increased and the micro-DVI video port was replaced by the Mini DisplayPort. A mid-2009 refresh, introduced alongside the MacBook Pro family, featured a slightly higher-capacity battery, and a faster Penryn CPU.
A few days ago I spoke to an Apple customer service rep about getting an adapter. I first went on line to see which one I needed, wasn't sure so I asked for professional help. After twenty minutes, after being on hold for about fifteen minutes, I spoke to someone who didn't seem to have a clue. She put me on hold and then got back on the line to tell me which adapter would work. I needed an adapter for my older printer, so one end had to fit into the back of my new Mac and the other fit the printer plug. The adapter arrived today and it was too small at the computer end. I called Apple back. To make a long story short, I spoke to five people - all of them useless. I was wondering if I was speaking Klingon because nobody seemed to understand that I needed the adapter to plug into the back of my computer and that the other end did fit my printer. They kept assuming that the printer end was the problem. I was passed on to a supervisor who was just as clueless. I was then passed on to someone who was to source the right sized adapter for me and she was the worst of the lot. I can't understand how a company that makes my computer has no idea which adapter I would need for it and after five people, finally one of them realizes that Apple doesn't make them. I got all my other adapters at The Source and they fit perfectly, unfortunately they no longer carry this product. The worst customer service ever and not once did anyone say to me to return this item because I was recommended the wrong size. Not once did anyone offer a refund. I sent the stupid thing back this evening with a note for them to 'stick it where the sun don't shine.' Go anywhere else if you need help with products for your Mac - Apple customer service reps don't have a clue.
On June 10, 2013, Apple released another update in the same form factor as the 2012 model during the company's Worldwide Developer Conference (WWDC). The 11" and 13" models have a minimum standard 4 GB RAM, with a maximum configuration of 8 GB. Both models are powered by the Haswell ULT 1.3 GHz dual-core Intel Core i5 processors, with Turbo Boost up to 2.6 GHz, while a 1.7 GHz Dual-Core i7, with Turbo Boost up to 3.3 GHz, option is also available. Each model's storage standard is 128 GB SSD, upgradeable to 256 GB and 512 GB SSD. Due to Haswell CPUs, battery life has considerably improved from the previous generation, and the mid-2013 models are capable of 9 hours on the 11" model and 12 hours on the 13" model; a team of reviewers exceeded expected battery life ratings during their test.
