The Echo is an Android phone that can mimic a tablet. Kyocera added a second 3.5-inch touchscreen that snaps into place alongside the primary one; together the screens have a total resolution of 960 by 800 pixels, only slightly fewer than a seven-inch tablet. By default, the pair of screens share one image, be it the NYTimes or Hulu. App creators are using the developers' kit to code games that play on both panes—for example, an overhead view of a pool table up top and a first-person view on the bottom. Free (with contract)
make it detachable so you can have a phone on you always and leave the add-on screen as an accessory
They have been talking about the Echo for what seems like years now. I like the idea but it seems clumsy in its implementation. It has been so long I would suggest scrapping it and start working on the Echo 3, one is so old we can probably skip number 2 and jump ahead. If they make one with the new Tegra multi cores that are coming out it could be a cool device.
