Though it sports the same resolution as PocketPC's, its resolution is considerably more Palm-like in that you can actually read it. We're talking QVGA or Quarter VGA, aka 240x320. There'll be a lot more detail about this to come, but suffice it to say the screen is stunning and the Graffiti area does indeed slide out of the way to make room for more data. And yes, your strokes leave an ink trail until you lift the stylus and the character is recognized. The screen can be rotated, if programs permit, and legacy programs that don't handle the special interpolation method can be run either center screen or upper left corner in 160x160 mode.
Icons can be large or small.
In small mode, they fit four abreast. I'm somewhat overjoyed about that. The power supply consists of four AAA batteries, or you can use a lithium-ion battery pack. There's a jack on the unit for a power input, or it can be charged through the cradle. The power input can also bypass the AAA's and run the unit directly.
