I started out with a Kobo, transitioned to a Nexus 7 2012, and now have a Samsung 8" - I don't want to pay for a $600+ phablet with a screen too small to easily read a book, which my tablet provides and is primarily used for - as well as browsing the web and a lot of email (voice to text is convenient)
My phone is a device for calls and a camera combo that can do basic internet stuff if needed. My tablet has supplanted my notebook because it is so much more portable and powerful enough to do a lot of the notebook based stuff of years gone by. The notebook sits in the case like a the just in case fire extinguisher, waiting for that travel moment, which more and more the tablet has taken the place of.
If I am at home, I would much rather work on my 8700k desktop with dual monitors than the 15.6" laptop that cost as much as the upgrade to the 8700k.
Long live the $300 8" tablet!
