When we move homes this summer, my plan is to have a MS Windows free house-hold. Both of our Windows Media Center PCs have stopped working and I haven't bothered to figure out why - (interestingly, my Tivo Series 1 from 1998 still works). Media Center and its Windows problems just became too much hassle -- TV is suppose to just work, and adding Windows to the mix breaks that rule.
iTunes and iPhoto do a great job sharing content across Macs, I figured our new house should be a Windows Free environment. With iTunes TV Show, I can get the 2 shows I watch in a commercial free format, and I can use my Tivo in the rare occasion we are watching live TV.
Macs Minis could power up the living room and bedroom TVs, iMacs for the den, kitchen and homework areas, and a PowerBook and Mac Book Pro for mobility.
The problem is that I am running into heavy opposition from my family. My daughter flat out refuses to switch - "there are many more educational software for Windows than for the Mac, and I can't use MSN on the Mac." My wife just finds OS X harder to use and doesn't want to bother with web site incompatibility with Safari (a lot does not work w/ Safari forcing you to use Firefox and losing out on .Mac synchronization). Then there is the video conferencing issue - our friends and family members use Windows Messenger, and you can't video conference with them via a Mac. My hope here is that Skype will support cross-platform video conference soon, but it is not available yet.
Maybe the solution is to let my family members self-manage their own Windows PC; in about 30 days or less, the machine will crank to a halt and we would have a virtual Windows Free household after all.
