Will mobile takeover desktop?
I personally think desktops and mobile will work together, and neither will takeover usage over the other significantly. Desktops for more screen real estate and granularity where mobile for on the go and time crucial tasks.
Big desktop fan here. I rarely use mobile apps. It's more about consuming content than creating content. For me at least this is and will be a desktop domain. Maybe for some, an iPad might work, but isn't it also kind of a desktop already? :)
Easier to consume on mobile and produce on desktop.
