Neato weather station thingy

At the MIT Swapfest a couple weeks ago, I chanced upon a GE Weather Station. This little toy has a wireless sensor you mount outside, and a display to sit on the shelf inside that displays inside/outside temperature, humidity, time, high/low temps since last reset, etc etc.
The best part of tihs is that I picked it up at the flea for a mere $9, rather than the $44 I see it online for. It’s sort of neat to note that this technology has gotten so common that it shows up in flea markets (new in packaging!) for basically pocket change.
