Impressing handcraft / engineering work, although with weight of ~1.5 kg it's not particularly lightweight (twice iPad's weight). What about battery life? I'm surprised if more than 2 hours. Personally I don't understand what's the big deal to have exactly 1280x720 pixels in handheld device. Yes, in theory you will get wider field of view compared to e.g. iPad's 1024x768 resolution, assuming you adjust your watching distance accordingly (to keep visible pixel size same), but it's not that big difference, given that tablet watching (close-distance) is always big compromise compared to big screen watching, due to fact that eye is relaxed when focused to infinity.

  If this is an external battery pack, don't forget to add its weight when comparing the iPad to his device. I think it's an amazing hobby project, but it's quite clear that getting ten hours of battery life out of a tablet is a tricky proposition involving tradeoffs from top to bottom of the hardware and software stack. e.g. Flash, pre-emptive multi-tasking :-)

This guy single handedly built a tablet that's only twice the weight of the iPad but considering the specs that's actually really good. The screen is 13", for example. He built this himself! It's his first go at it. Imagine what he could do on his 2nd or 3rd try. If you're going to compare specs with the iPad then you should compare the engineering efforts, time, and money spent as well.

  Hmm downvoted, must be because I was about 15% out - CarbonPad is 809cm^2 whilst iPad is 460cm^2 face area; sorry about that.
