In last year’s Holiday Gadget Guide, I reviewed the wonderful then-new LEGO MINDSTORMS NXT system. It’s a year later and my admiration for this product has only grown. It has been enthusiastically embraced by robot hobbyists and professionals, educators, kids of all ages, R&D departments looking for quick n’ dirty prototyping components — 1,001 uses. It’s also been embraced by publishers, who’ve followed the product with a felled forest worth of books. Three of may favorites are from No Starch Press (disclosure: O’Reilly, the publisher I work for, distributes No Starch titles).
