Lamp switches can be kind of a pain—either you can't reach them comfortably, they break within a few months, or they just take a lot of force. With an inexpensive touch switch, you can turn any metal lamp on and off just by touching it with your finger.
DIY web site Instructables has a guide to hooking a touch switch up to your metal lamp, and it's a pretty cool tweak—not to mention surprisingly useful. The touch switch requires digging into the wiring of the lamp, but it shouldn't be too hard, even if you aren't an electronics guru—the tutorial on Instructables coupled with the touch switch's manual should be more than enough to get you set up. Hit the link to see more about how it works.
