If you brought a big, conventional laptop with you to college, you're probably regretting it right about now. It's not fun to lug a heavy machine and your textbooks around campus. You may have an easy way to try out something a little kinder to your back, though. Google has unveiled the Chromebook Lending Library, a demo program that lets students borrow a featherweight Chrome OS machine for a few days. So long as Google is on the school grounds, the system is yours; you can take notes in class or just catch up on Netflix in your dorm room. The Library arrives at both Syracuse at Walnut Park and Texas State University next week, and it'll swing by other institutions in the weeks ahead. The big catch? You can't actually buy a Chromebook from the Library if you're enamored with the experience -- you'll likely have to venture into town to pick one up.
