I played with the Wgrill yesterday and was able to pull it up on my windows vista laptop and my itouch- the screen is to small so not very useful. I tested it outside while I monitored it inside. Just used the ambiant temp outside to see how the two probes monitored the outside weather. They were within 1 degree of each other or the same. Range was OK but will try to mess with the placement as it was behind a brick wall and I didn't get a full 3 bars from the signal. I'm cooking tomorrow night and will give some additional insight.
