My biggest disappointment for most chromebooks is not the functionality--they are designed for a specific sort of usage, and I totally get that. But...I can't fathom why they were designed and have such low battery life (and with such a relatively hefty weight). I see how you can hit 2.3 pounds for a chromebook--that's a reasonable weight--I just don't see why the battery life is so abysmal. For such a low power device, I would expect, like, days of usage, not just 6 hours. How difficult would it be to integrate a larger (and yes, heavier) battery to get you super long usage? Not very hard. I mean, I know the price point and target market is totally different, but let's take the MBA; it weighs the same, and gets at least 50% more battery life, all with a more powerful processor and full desktop functionality.
The guts of the chromebook are essentially a smartphone with a keyboard and a larger display panel. It has a 2300mah battery. My phone has a 2100mah battery. You could easily double the capacity without a significant cost or weight, and have a truly usable all-day device. This 4-6 hour usage is sub-par by today's standards.
