CDS-810S - Bamboo Slate Large

The one improvement that I'd like to see is a built-in detachable clip, otherwise you could use your own clips or put a few pieces of paper in the clipboard's slit to hold the pad steady.While the ink is a standard refill, the pen is proprietary so if you're not a fan of it then...tough. Works just fine for me but I have heard people who grip the pen further back accidentally retracting the nib via the twist-action..looks more like an artist's grip than a scribe's to me.Anyway. I'd get the A4 if I want max usability. That puts most office paper within the scope of this thing.
