it doesnt work well as a tablet or on a desktop how can it be a good bit of design!?
That's just your opinion. I respect your opinion, but I don't have to share the same opinion.
My opinion is that it does the job. It's clearly v1.0 and will improve. The Desktop->Start Screen is a jarring transition. Also as there are very few apps I find useful in Metro I rarely use it. My desktop experience has hardly changed.
putting it down to people just not got use to it sounds like poor design too, intuitive, instinctive, two things it is not!
Not necessarily. It's a change, and a significant one. The option is no change and that leaves us with Windows 7 which is still a cracking OS.
When 6 speed boxes came out in cars it wasn't intuitive and instinctive for me to change to 6th when I was used to 4 or 5 gears, but there will still benefits to the change and I learnt to adapt. Not as much fun when you put a 5 speed car into reverse on a motorway tho
But people react differently to change. The problem with MS OS's is that they try to please all of the people all of the time, but ultimately for them to move forward they need to make more significant changes, separate products might have been an answer, but they chose not to, no doubt with good reason for them.
I'm currently playing with a Pi, but have little experience with Linux, doesn't mean it's badly designed when I can't do something as quickly and easily as I could in Windows, it just means I need to learn how it's done on a different OS...and it's bl**&y frustrating for me!
i duno a fair test maybe if they were all mac users?, or maybe really old people
But more importantly what tasks? As I said before most things can be done without the new UI being a factor, and if it's really simple things like open mail, calendar and internet then I can't see how using the start screen with big colourful icons would present a problem, unless you wanted Win 8 users to have to run x86 legacy apps...I guess what I'm getting at is I don't think it would be easy to get a level playing field, or by the time you did the changes wouldn't really play a significant factor.
