Today I was at our bookstore grabbing my copy of Goldstein and Jackson for THAT semester of grad school and I decided to pick up some notebooks and paper too. I've come to realize that I've become very picky about paper and pencils! I look back on my undergrad work and I can barely read any of it and the paper is dilapidated and old looking; in other words, useless. It made me realize that in all honesty, I'd pay... $20, at least, for a mechanical pencil and lead combination and at least $20 for a notebook if they could really preserve my work. I hate these notebooks where some pages are stuck together, have faded areas, are easily damaged, seem to erode easily... I honestly feel like googling "deluxe paper" and looking for what I find. I'm also quite picky about keyboards. What have YOU become picky with?
