I've been needing a new computer for a while now, and I recently ordered a 2011 macbook air 11" w/ 4GB RAM, 64GB SSD. Unfortunately, it will take about three weeks to arrive. Although I'm excited for my first mac, D) I can't help but feel like I've been had. It seems that the 11" macbook air doesn't get more than 60-70% of its advertised battery life. Also, almost every other computer in the ultraportable class has much better internals (full-voltage processors, upgradable RAM). To clarify, I am not comparing to those "ultrabooks." Specifically, I've been comparing the macbook air to the Lenovo X220, which outclasses it in almost every way. Now that I consider it, I actually like the look and feel of a sturdy business notebook better. To boot, apple is ridiculously proprietary with its hardware, making repairs and upgrades exorbitantly expensive. As a side note, I personally think that win7 is just as good as OS X, and that is obviously not the viewpoint of most members here. To recap, my main point is that although the macbook air is undoubtedly a wonderful machine, it lacks battery life, the raw processing power present in other ultraportables, sturdiness, and user-friendly upgrades/repairs. That said, I'd like to see what current macbook air owners have to say about this. Please try to keep your responses as mature as possible and back up your statements. I've regrettably seen some undignified rants on some threads here, and I honestly don't want that kind of thing. I'm not an apple hater, just an unsatisfied consumer.
