I'm truly sick of intelligent people making this blunder. A tablet PC doesn't do the same thing. They're not the same device. A tablet PC has a short battery life and is not designed for wear-and-tear the way an ebook device is. On the other hand, (good) ebook devices use eink displays that are at a glance indistinguishable from real paper. They are designed to be lightweight and durable. They are specialized devices.I don't understand why people would buy this at ~$400. May as well just go and get a low end tablet pc, which you could use for a multitude of other uses.
P.S. Where can you find a tablet PC for $400?
