If you don't need an ebook gadget right now, Boox is about to release the Boox Picco as a direct competitor to this. It's in between the X3 and X4 in size, but has a front-lit and potentially higher resolution screen.

I have an X4 Pro (219 ppi) and I use 14pt font because letter widths are pretty uneven at 12pt and on a screen this small I wish I could use my preferred tiny font size. Other than that, it's great.
