Triton Submarines makes 2-man and 3-man subs designed for 1000 or 3300 foot depths. "The 3300/3 played a major role in the expedition to capture the first ever footage of the Giant Squid" which a few of you probably saw on the Discovery Channel. They are one of a handful of companies designing models capable of visiting the Challenger Deep (repeating the feats of the Trieste in 1960 and James Cameron in 2012).
I wrote an Android app that allows me to tell a UPnP MediaRenderer (like a WD TV Live +, although that particular unit has many shortcomings) to play a movie file that lives on my phone. This sort of functionality is already available in a couple of off-the-shelf androids and will probably be a standard feature by the end of 2011.
I'm told the big advantage of the Apple version of UPnP is authentication, which is not mentioned in the UPnP specs I have read.
For me, I never got a Tivo because of the cost. You need to purchase the equipment and then pay a monthly fee.
I have a MythTV, and ever since that debacle with commercial builders flouting the terms of service at Zap2it Labs I have been paying Schedules Direct for my channel guide.
The lesson from Schedules Direct is that plenty of people who use Open Source are willing to pay for a service that has value.
