Netbooks have less speedy processors but at only 12" are nice and light. Cheap too!
17" laptops can easily weigh 10lbs and are a
pain to carry around! Don't do it unless you're very strong or need that physical size for some reason.
I've got the nicest balance between them, the 13.3" (or 14" for some.) still small and light, yet still rather powerful. 8-hour battery life too! Not a $1000 "ultrabook", just the same $400 from Acer.

>>> THIS smaller netbook...might be lighter options that get the job done.
