One of the best things about the 770 is the battery life. Whenever I fly, I load it up with Project Gutenburg eBooks for when the in-flight entertainment is too bad. On my last two trans-Atlantic flights, I read Pride and Prejudice and Accellerando on it, and the battery monitor showed about half full by the time I finished.
The screen is still one of the machine’s best features. At 225dpi, text is crystal clear on it. I’ve only seen one other screen with the same pixel density, it was made by IBM and priced this way: "Call, but make sure you’re sitting down and have a large brandy ready for when we tell you how much." Hopefully they’ll make their way into laptops in the next few years.
