Mobile is changing web usage patterns
For a long time the usage pattern for the web was a pretty standard. People were using the internet at a rather simple to understand scenario, behind a desk using a computer. But with mobile usage now surpassing desktop usage, this is the norm.
This is clearly a megatrend that is shown in analytics data, but everyday usage patterns. Nowadays having access to the internet everywhere and at any time is addictive and powerful. This is why your design and usage patterns should take this into account.
The designs on mobile devices are now very utilitarian and few dare to try gimmicks. This is why the value of the desktop design is questionable nowadays.
