Of all the things that impress me about the iPad so far, definitely one of the biggest is its battery life.
Most of the time when companies (including Apple) claim a certain battery life, actual product usage never comes close to that because those are under optimal conditions using minimal settings. For example, I have one of the new MacBook Pros which Apple says will get 8 to 9 hours of battery life on one charge. In reality, using it as I normally would (screen about 60% brightness, two browsers open), I’m seeing more like 5 to 6 hours (still great for a laptop, IMO).
With the iPad, Apple claimed it would get 10 hours of usage on a single charge. In my usage this past week, that’s absolutely true. In fact, it might even get more than that.
Other reviewers noted this early-on too, but I had to see it to believe it. Now I have. And now I do. It’s awesome.
