As I mentioned last week, I'll periodically be telling you about some of my favorite places to get useful gadgets. This week, I want to point you towards ThinkGeek, a site that's generally geared towards the sysadmin crowd, but has tons of great products for the rest of us—even if we don't necessarily get the jokes on the T-shirts they sell. (Like this one.) For example, there's an entire section featuring caffeine-related products (including, weirdly, lip balm). And they sell all sorts of cool office gear, like a squid-like power strip replacement that actually fits your bulky plugs and a pair of AA batteries that recharge using a USB port.
