when i was doing my honours year i ended up with 8 kilograms of journal articles printed out, poor trees, so i am thinking of getting an e-book reader. I have heard of Amazon's kindle but it seems closely linked to their store, i want to be able to read pdf files from scientific journals and make notes in the margins etc. and preferably sync or copy annotated versions back to my computer.
i want the reading on the couch with a pen experince of paper print outs, but without the many kilos of actual print outs.
