Windows RT - The hottest technology to avoid for 2012-2103.
First of all the name is ugly (I'm thinking the guy who named Zune and Windows RT must be related)
Secondly, we all know that mobility is the future, cross platform integration is completely awesome, and Microsoft has the potential to tap all markets. But, It doesn't need to be done by sabotaging the existing Windows ecosystem. This puts Windows 8 and Windows RT as the top products to avoid.
Also, did I mention that Windows RT doesn't play nice in the Enterprise environment? First of all, either they rushed this to market and didn't have time to implement AD, OR they purposely left it out so they can milk a monthly fee for management tools.
Bottom line, sabotaging what you already do with excellence, is not a good way to try to drive your stock price up. Better way is to force a change of leadership, someone who is a bit more creative, and can come up with solutions that are good for all markets.
Edit: While I am up on my soapbox, I might as well mention Windows Media Center for a second. This is not a good product to kill. The reason why I like it so much is it is something M$ pioneered in. Are they really going to give this market away to Apple and Google? They should be a front runner, and trying again until they succeed. As it ties into Windows RT and mobility, A nice digitally connected lifestyle with WMC pulling in media from all sort of different hubs, Cable, OTA, online etc, and distributing this out to all connected mobile devices + extenders, would leave no room for an Apple TV in my house. Unfortunately, they've already missed it, even though they've been in the market for 10 years. Sad, really sad.
