My PC sits in a place behind my table which isn't easy to reach, and I have my keyboard and mouse connected to the built-in USB switch in my monitor. Because the monitor turns off by itself to save power, there's no quick way to wake the PC from suspend mode (e.g. by pressing a key). However, I've accidentally found that turning off my desk lamp wakes the PC up! So just toggling the lamp and off will do the job. I guess it's somehow because the PC and lamp are connected to the same extension cord. The only inconvenience is that I sometimes forget to turn the lamp off before putting the PC to sleep at night. It's pretty reliable - at least more reliable than the wireless IKEA light button in the kitchen...
