Laptops, mobile phones, game systems, computers — they've all got different screws or bolts, and require different screwdrivers for each. Unless you've got this screwdriver with a swap-able tip and the 30 electronics-friendly tips that go with it.
One of these tools goes for $US5.34 at Meritline, which is not a bad price at all when you consider that its tips fit a Nintendo DS, a Sony PSP, most laptop and desktop case and drive screws, and probably any other kinds of electronics you'd want to take apart. But you can often find this tool on the cheap too, as we discovered it ourselves through a SlickDeals.net forum post. Keep an eye out for it — item number 92-177-001 at Meritline — but also consider the regular cost if you've got a screen replacement, hard drive swap or other tech project coming out, and you're never quite sure where your tiniest screwdriver went off to.
