Given the same volume, a tablet has more space for batteries than a laptop. A laptop has to use space for the hinge, keyboard, trackpad, peripheral ports, and display. Worse, you can't fit batteries behind a laptop display without ruining the balance. On the other hand, a tablet is practically a screen with a ton of batteries behind it. Here's some real-world data: The 3rd gen iPad has a 42 watt-hour battery. The 11"…

Intel chipsets and processors have gotten very, very good with power management. With reasonable screen brightness and Wifi enabled, my X220 idles at ~8.5W. With a 90Wh battery this gives me ~10 hours on a plane, which is more than I can handle in one go. A tablet TDP (iPad) is about 5W which is 2x better. This is 2X better for a device with smaller screen, no spinning drive, no keyboard, and a much weaker processor.…

It only has a 4,000 mAh (15 Whr) battery, smaller even than Nexus 7's 4,300 mAh battery, and considering it also has a much larger 12" screen (more than twice screen area), the battery life would also be smaller than Nexus 7. Nexus 10 has a 9,000 mAh battery, which is also used to compensate for the 2560x1600 resolution. iPad 3/4 has 11,500 mAh and it's pushing 1 million fewer pixels for comparison's sake. But I agre…

I hope Google will partner with ASUS for its next chromebook. Or even Lenovo. I had bad experience with Samsung hardware.

I should be able to figure this out for myself, but I will ask anyway: is 16GB SSD really enough to support Ubuntu and a development environment? At a minimum, I would need Ruby+JRuby+Clojure+editors an an IDE. I could probably live with just 4 or 5 extra GBs for project files and whatever my current writing project is.
