The biggest thing I've experienced with cheap tablets is that the underlying storage medium of the device just sucks, and there's often no good way to actually know how bad it'll be when just looking at a spec list. Auto-updates from the Google Play store of the apps will quickly wear out the on-board storage and lead to everything going extremely slow until it finally dies. Also, usually they have extremely bad screens with terrible viewing angles. Using them as something you're going to stare at for hours is miserable. Sure, the spec list says it's a higher resolution than the paper-like e-reader, but in practice the paper like display is far more comfortable to stare at for long periods of time. Spec lists don't tell the whole story.
