HP and Office Depot have teamed up to offer free in-store electronics recycling between July 18 and Labor Day. Just bring your old computer/printer/monitor/what-have-you (any make) to an Office Depot store (limited to one computer system or other device per customer per day) and they will take care of the rest (word to the wise: wipe that hard drive first!). Dell is offering a similar service, free for people who buy one of their systems online, and at a small per-unit fee for those not buying new computers.
