an alternative to the laptop for backpacker ?

i don't want to make advertising, but i found an affordable product for backpacker : a 12 inch tablet with a weight of 520g.
When a 10 inch tablet is 400g, and a 13.3 inch laptop is nearly 1kg, a 12 inch/520g is a good screen size weight/ratio. What do you think ? (Note : no direct advertising for a product, only features and why it could be a good product for backpacker)
