Dan is right - Windows Updates reboot your PC, and you have to get the updates - although I am not sure why... If your home automation setup worked great when you set it up in 2009, why do you need to get Windows updates weekly
And the answer to Dave W about cameras and movies on the cell phone is simple... It makes money for the wireless carrier.
When cell phones first got cameras, I didn't get it AT ALL - I used the phone to make calls, period. Then one day I took a picture with it, and it came out pretty good... so I wanted it off of my phone - and it hit me... In order to get the picture off the phone, you either needed data service for an extra $20 a month, or pay the data fee to email the picture off the phone - unlike a digital camera... So it was confirmed that they give us free abilities on your phone to get additional service fees from us all. Brilliant!
