Having found both types of device in the rubbish, intrigued by author's comparison. Except there is no comparison.
Starting with the Elonex netbook, originally given away by Orange to tempt users to eat expensive mobile data via a dongle. This failed to work using the screwed-up Ubuntu installation on board (confirming my then prejudice against Linux) but booted from an external CD drive to install XP. Apart from a horrible keyboard and exhausted battery, has proved a usefully portable tool when visiting friends to fix their systems.
Next the no-name Android (model name AC1 or something similar) 10 inch tablet which turned up a couple of years later. First clue to its lack of utility was the inclusion of a stylus. Without that the screen is as responsive as a sloth with a hangover and, even with, is inaccurate enough to make text a pain. Add strangely reluctant network socket, weak wireless and battery -- plus the weird phone-based version of Android -- and the thing is rapidly gathering dust.
So -- netbooks good, but for a nicer experience stick with better known brands. Cheap iPad knockoffs, avoid, even if they are cheaper than cheap (i.e. free)
