I started with an Ainol Nova 7, cheap Chinese tablet, and pretty much spent more time tinkering with ROM's that actually using the device.... After a year of not using it ever, I randomly decided to buy a Nexus 7 2013 and it took over a lot of home browsing and videos. A few months later I added a Venue 8 Pro to my list of devices and now I have little need for any other device, including my gaming laptop outside of actually gaming, lightroom, and the massive amount of storage...
So, from my experience even if the OP's first tablet doesn't fit his usage doesn't mean that no tablet will... but of course, YMMV.
