WiFi

WiFi can be both a blessing and a curse. For example, the hotel I'm staying now. For some reason my room's a dead zone, where I only get one bar of signal. And sometimes that goes down to zero, for example right when I'm saving an e-mail. And sometimes I have to walk around the room to find a signal.

Oddly enough, the rest of the hotel seems OK -- I've walked down the corridor in both directions and the signal is only bad right at my room. I'd move, but I'm not staying here long.
