I too bought this device around Christmas time. Had no trouble installing it (I use Windows 7 PRO), but like others here there seemed to be no connectivity between the USB device and the display device. I got hold of a nice lady at Sharper Image who told me that it could take from 30 - 60 minutes for the two devices to communicate with each other. (I watched closely to see if the two were passing handwritten notes in order to account for such a slow speed; no notes, but they must be using 2 Baud to do so.) Anyhow it all works, except:
1. The "Update" date on the screen never shows anything.
2. Some of the predicted temperatures are bizarre, especially the "lows". Had several instances when the display showed single-digit low temps when the weatherman was saying upper 20's.
At least the general weather prediction icons seem to be reasonable.
This device is a mixed bag; don't give up watching your 11:00 news and weather if accuracy is important to you.
