I loaded up my iPad with apps, this being one of the first. Works very well! The device does not work well in direct sunlight, but most computers don't work well in direct sunlight.
I can go sit under a tree and it's perfectly viewable. This device is quite extraordinary, I know the haters really hate the bloody thing, but I already have it doing an incredible number of things and it's beautiful hardware and a delight to use. It's simply far far beyond a device like the Kindle DX.
