I have been really excited by the reviews thus far about scalability of Win 8. The news that it will run from servers to tablets had caught my imagination as a one stop solution and a break from existing scenario. So I took the plunge when the customer preview was launched. I had to make sure that I did not lose my existing functionality so a dual boot was the only option with my existing Win 7 ultimate x86 machine. Good news was that people had successfully done a dual boot installation. So did a bit of reading and did the disk re-partitioning to create space for win 8. Downloaded the consumer preview .iso and went ahead with the installation. After installation, first impression was good on seeing the famed 'metro style' interface. Then I hit a roadblock. Where are usual buttons and bars you see in win 7? Bit of trial and lots of mistakes finally got me into the grove and was able to do minimal work as I was in hurry. Looking for shut down and I was flummoxed again. No "start" button to chose anything. After a short experience all I can say is that it is going to change the way people use computers, yet again, and will have a rather steep learning curve for people used to tinkering beneath the hood. If anybody is interested, I can post the complete process for dual boot selection.
