In parallel to Abhishek's post I thought I'd ask how others are getting on with their Ultrabooks and Win8, good and bad.
General - I took the plunge and use the Ultrabook as my primary PC - it's the only way to really learn. The more i use it the more features I like in Win8 - I hated win8 when I first loaded it in a VM as I had to Google/Bing how to power down (Win+i) but with use it has become a positive experience. Boot times are wonderfully fast. The Ultrabook is sleek, fast and feature packed and the Intel tools are great. Microsoft Visual Studio is neat but don't get me talking about Microsoft customer service.....
What's missing at the moment - documentation is sketchy and things can be a steep learning curve which is why a good community helps. The Intel guys have pointed us here so let's use it.
What won't happen - Corporates will not move to Win8. It is too much of a leap for them. Many are only just moving from XP 32 to Win7 64 so I don't think they will move until Win9 or whatever it will be called. The technology jump is like moving from DOS to Windows 3.0 meaning it will take time for power users to adapt and IT to be sure it's safe. This isn't just 'not until SP2' because corporates have screens that have no touch and you really need touch. User pressure will eventually sway things but that will take time.
What will happen - Ultrabooks and tablets running Win8 need good apps that use the power of the devices so we need to make it happen.
If anyone's going to Swindon for the UK Sensor Technology Roadshow let me know and we can have a chat.
