6. Kobo Mini
If space is really at a premium, you can opt for the Mini. It’s a very neat gadget that fits the pocket better than rivals thanks to its five-inch e-ink display. There’s no front light (but, hey, books don’t have those either) but it has a decent touchscreen interface – if occasionally a little sluggish. The power switch is more conveniently placed on the top edge, unlike the Kindle’s easy-to-turn-off button on the bottom. Kobo’s Reading Life feature includes stats for how much reading you’ve done, which seems to me a recipe for guilt. This reader, like the Nook, is only available in wi-fi versions so you’ll need to be in a hotspot to download that next book in a hurry. This ebook reader is also tremendous value.
