But seriously, it always makes me angry when I see the notebook computers that some schools force their students to use. Big heavy 15" models are stupid to be carried every single day even by adults, let alone small children. You would think that inexpensive, small netbooks should be a no-brainer.
Netbooks are out of the question because they are almost impossible to work with on a day-to-day basis (particularly for students with vision problems). That only leaves small, inexpensive laptops, which as I understand it don't exist yet. Ideally you'd be looking at a 12-13" laptop, but they're too damn expensive when you put them up against the 15-17" monsters. To be honest a 15" laptop isn't that big a deal, I have one sitting on my desk which is approximately 1.2kg with the battery in, vs. 1.1kg for an average size maths textbook. Hell, I've got a soft-cover physics textbook which is 2.1kg, and a couple of hard-covers which are presumably much heavier.
Oh yeah, and just for the record here is an approximate cost breakdown of current secondary laptops in Australia (figures given to me by a tech guy from a high school):
Hardware: $1500
Software: $1500
To be fair, that is for a Dell machine rather than the Acer which the State Government were pushing, but in any case the OLPC reduces hardware cost to $234 and software cost to $0.
