Last week, the new MacBook Air arrived, and I wasted no time in putting it to good use. I bought (and reviewed) the first one back in February 2008 when it was released I then upgraded to the next iteration in June 2009. It must be absolutely reliable and available constantly. My laptop is my gateway to everything I do. While I may be directly or indirectly responsible for thousands of servers, desktops, and laptops, the one that matters the most is the one I'm using to manage all of those resources. When it comes to laptops and desktops, nothing matters to me more than reliability.
