but if majority of your lead designers never in their lives used the taskbar they are surprised when replacing it with a dock causes outcry
That, likely, highly depends on your industry. Designers doing mobile application design, as well as web design from my limited experience tend to steer towards Macs. Even within my college the entire graphics design department was Macs. Of course if you are working on a Windows based product you'd in theory expect the designers to use or be familiar enough with Windows but you may be surprised.
I'd be curious to know if there are regional (country) differences in this.
It’s tragic that because of elitism Microsoft does not hire those designers and instead hires designers who don’t care about their product.
If you want innovation, how about performance, accessibility, compatibility,...
When you have over a billion users worldwide there's an expectation that you don't treat your product like a startup's art project. I haven't met a single person who wasn't completely confused by Windows 8's UI or who liked the changes. I've seen lifelong Windows users spend 10+ minutes desperately looking for the shutdown button.
There's "inspiration" by different products but in the end you need to know your own product in order to improve it.
And I'm not an indestructible 20-year-old either :)
All laptops have a very special feature called external monitor support. And for some laptops, you can even buy docks.
Boom!
I know, it's amazing.
