Q: The answer to your question is no.  There is no absolutely definitive evidence to date.  We do have very strong evidence that significant amounts of water once existed on the Martian surface, and some recent results show that Martian water may still exist below ground, and under heavy packs of ice.    There are many scientists who believe that Mars once had a thicker atmosphere, which would have made it a considerably wetter and warmer place.  Given this, and the ability for solar system bodies to seed each other via ejecta from large impacts, Mars could very possibly have been seeded by Earth or vice versa many billions of years ago.  Still, we're not sure if life exists or every existed there.    The most recent chapter was the recent discovery of methane there.  Methane can be created by non-biological processes, but we have not observed the right conditions for this on Mars.  Another possible explanation would be a biological origin for the gas, potentially from colonies of microscopic organisms in the soil.    Given our current rate of deepening understanding, we will likely solve this mystery sometime in the next 50 years, but as of now we simply don't have enough evidence to constitute "proof"

Q: Easy, SnapStream, or I think it's now called BeyondTV, there was an article written on it in 2002 on tomsnetworking.com, great article: http://www.tomsnetworking.com/network/20020423/\n\nA little more than $50, but $69.99 ain't bad. If you don't already have a tv tuner card for your PC then get the bundle that comes with it.\n\nI'm not sure but I think the XP Media Edition PCs have similar software already built-in as well.

Q: I can't tell you which of the many are best, but I can tell you about one I lived in briefly.\nI lived for a month in the Avalon at 4th and King. I was put up there as a corporate apartment. While it was fine, it was relatively expensive, and the rooms were small. It also had one of those rooms that served as kitchen, dining room and living room all in one. I'm not fond of these kinds of rooms, which are particularly American. The smell of cooking, people watching TV, people eating -- these all seem like activities that should be separated from one another. Call me old fashioned.  \nThe Avalon had a big gym, however, which was very good, and concierge service, which was very convenient. Most of them were very friendly. One concierge even hugged me when we left and said she was going to miss me!  Also convenient was its proximity to the Caltrain, the Safeway across the street and the Starbucks. But if you crave culture, this ain't it: everything is a chain store nearby.\nSo depending on your budget, your need for convenience and culture, and your tolerance for small rooms and/or omnirooms, it may suit you.
