Welcome to IRL, an ongoing feature where we talk about the gadgets, apps and toys we're using in real life and take a second look at products that already got the formal review treatment. Hi there, folks. It's that time of the week where we share our close and very personal experiences with various gadget paraphernalia. This week, Brian makes the switch from the Nook Simple Touch to the fourth-gen Kindle, Ben explains why he'd rather replace his own laptop battery, thank you very much, and Don makes the case for a laptop bag that looks anything but.
