Students don't seem to look after their devices, specifically their laptops very well, and in my eyes netbooks though lacking in the full power and potential of a laptop or desktop machine, are seriously underestimated and undervalued for what they are actually worth.
There are five simple, 'off the top of my head' reasons to get a netbook:
The batteries last ages, regardless of what operating system you use;
They're surprisingly tough, because they're built small and compact, and there are rarely any loose points where you can push in, bend or appear fragile;
But it's not often you come across a younger person who plays games on the PC. Either they are within the browser, such as Facebook which has a high range of games and interactive content, or they are on their dedicated games console - more often than not an Xbox 360 or a PS3.
