We're pretty big fans of duct tape. The day we can't find a roll around the house for quick fixes is a pretty dark day. We even buy it in fancy colors (red duct tape for special projects, blue for serious ones).
And the only reason we haven't plunked for an iPad is the cash. But let's say we sold our plasma, scraped together all the change in our couch, sold back some CDs (we'd already ripped), and used our last spare penny for an iPad. What would we do to keep our investment safe?
