Very pretty, and I love the idea, but the video implies to me that erasing might be difficult. Note how much they had to wipe to erase brand new writing. Either that's a bunch of grooves, or it's just a fair bit harder to erase than e.g. a normal whiteboard.
Use an old (red!) marker. Leave it on for a month. Then erase it and show me it erases well (with alcohol cleaners is fine, whatever works). That's real world use, not write-now, erase-in-seconds. Until then, I trust nothing but glass to actually erase, and have yet to see anything but glass beat standard whiteboards.
