I don't intend to play down what you're doing here because it's very significant. You're using the 770 as a remote display device and you're skipping the step of having to build a computer and install an operating system & software applications on it. That's a huge breakthrough.

An important point I want to make, though, is that the GUI in your pictures is a desktop GUI, and even at 225 dpi, it's clear that the content is A+ but the desktop GUI shown in the picture is D+. The desktop GUI is the wrong GUI paradigm for 770 type devices. What's clear is that apps for the 770, and for other devices like it which are sure to come, need to have new GUIs which are specifically designed for the applications that people want access to on their 770 devices. One example: tiny little pulldown menus that you can only operate with a stylus and great care are not good enough. That works on a desktop when you have a mouse but it doesn't work on a 770 with your finger.
