Boox has teased a tiny new ereader — and it's convinced me to put my Xteink plans on ice

• Boox has teased a tiny 'Picco' ereader
• It has just a 3.97-inch screen, likely making it a rival to Xteink devices
• It has a front light and a microSD card slot, and may well run Android, but lots of questions remain

There’s a lot more to ereaders than Kindle and Kobo these days, both in terms of brand names and form factors, and one such brand is set to offer a new, truly tiny form factor for reading on.

Boox (via GoodEreader) has just teased the Boox Picco, which is set to be the first device in a new ‘Tile’ product line. It has just a 3.97-inch screen, making it far smaller than even the phone-sized Boox Palma 2 Pro. In fact, it’s even marginally smaller than the recently launched Xteink X4 Pro.

Xteink has so far had the micro ereader market almost to itself, with this latest model having a 4.3-inch display. It’s debatable whether an even smaller screen is better or worse, but the Boox Picco may have some advantages over the X4 Pro.

Most notably, there’s a good chance it will run Android, since Boox devices typically do. This would mean you could install apps like the Kindle and Kobo ones, rather than having to sideload books as you do on Xteink ereaders.

Beyond that, we know that the Picco has a monochrome epaper display, a front light, and a microSD card slot, all of which are in line with the Xteink X4 Pro.

Great potential but lots of unknowns

I love the idea of the Xteink devices but my main hesitation in buying one is the lack of Android, so now I’m going to wait and see if this is a better alternative. But it might not be, as there’s still plenty we don’t know about the Boox Picco.

For one thing, arguably the USP of Xteink devices is their ability to magnetically attach to the back of phones, and there’s no word on whether the Boox Picco will be capable of the same. Still, this seems an obvious inclusion, so whether through built-in magnets or an optional magnetic case, I’d think it’s likely.

Also, it remains to be seen how attractively priced the Picco will be — the Xteink X4 Pro is $109 / £84 / AU$159, so Boox probably can’t afford to charge much more than that if it wants this to be a hit.

Plus, while Android is likely, it’s not guaranteed. With this being such a small device, Boox might opt for a simpler operating system.

Even if it does run Android, there’s a high chance that this will run a very old version, as is often the case with Boox devices. That would make it potentially less secure, and therefore something I’d be reluctant to sign into my accounts on. It would also mean that apps might cease being compatible with it in the next few years.

Still, I’m cautiously hopeful that this could be the tiny ereader of my dreams — there’s no word on a release date yet, but I expect we’ll learn more soon.
