Actually leaves room on your tiny tray for other important things ...

Purchased light for X4 but found I can use it for my Disc Notebook too.

Made an insert for my Disc Notebook to carry the X4 eReader using the supplied metal rings.

Shown here is my A7 and A6 disc notebook; I can move the insert to my A5 and A4 notebooks as needed.

I had two hours to myself, and used them to stay focused with my typewriter this weekend.

each has a slightly different purpose, and obviously the smaller they are the more portable they are; also like the fact that pages can migrate from smallest into the largest
