Tablets are more handy than netbooks. but less productive
Since you like to watch videos at the comforts of your own bed a netbook is the gadget for you. Processor speed of most tablets are below 1Ghz, usually around 700 to 800 Mhz.
A netbook on the other hand are equip with much faster processors to a point that even some netbooks are HDMI capable and can playback High Definition videos.
I really don't think tablets are high definition capable.
Lastly, ang item na gibaligya sa buy n sell section kay lacking of information. Like manufacturer or brand. It only mentions about android tablet. But there are a lots of android tablets at the market. So which one is he selling? And have you ever though why he is selling it? Perhaps he realize that a netbook is a much more profitable investment than a tablet.... just my thoughts, hope this helps you see the other side of the coin.
