I just switched from Kobo Aura HD (screen issues, poor customer service) to Kindle Voyage. I personally would not purchase another Kobo product (I have bought a total of four Aura HDs over the last two years, with only one remaining in working order).

The Voyage is probably the best built ereader sold currently, IMO.

The Kindle Voyage does have Wikipedia search option when you long-press a word on screen -- the pop up defaults to the word's dictionary definition, but from the dropdown menu you can chose either Wikipedia, or Translation (from a handful of languages).

Overall, I find the Voyage software more consistent and glitch-free than Kobo's, although there was nothing majorly wrong with Kobo's.

I would recommend the Voyage over the Kobo: The Voyage has considerably better build quality, the software is also a bit more polished, Amazon's selection and prices are generally better and in my experience, Amazon's customer service is dramatically better than Kobo's, should anything go wrong.

BTW, Kobo is tracking your reading habits, too. Both Amazon and Rakuten want to sell you stuff, but do offer some benefits in exchange. I do not believe the aim of such tracking is to "oppress" anyone.

You can purchase ebooks from different vendors and just use Calibre to organize your library, strip DRM and convert to a supported format, then upload to your device.
