Ofcourse, I'm fully aware that keeping those databooks up to date was not a cheap job in the early days, and definately not cheap today either since the world is constantly evolving. What I want databooks for is to get a general overview for products. I like browsing page by page in case I happen to find a nice chip or something like that. If it looks useful, I might sample it, build some circuits around it, and then continue doing so. For a situation like that, the pdf would certainly be the way to go to keep me updated with the chip-in-question's datas, but the book would get me into the "mode of knowing" about the chip. I'm still a hobbyist and I've yet got a long learning path to go, so I don't know even a tenth of a percent of all tips, tricks, ICs etc out there. For me, it's an eternal - but outrageously interesting! - jungle. For me, a databook would be my kind of machete to pacefully step forward along the path. Trying to walk the path using pdf:s would kind of be like tampering with quicksand. Stepping and struggling but without any grip. -- - Rikard - http://bos.hack.org/cv/ -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
