Likewise, I've seen similar in my environment. I think the difference is that mobile will enlarge the market, not displace full function devices - it's not CD killing the cassette tape (as the original article author seems to imply). Systems catering for mobile consumption will see increased use, but that doesn't mean decreased use for those not.

The change is presenting as a line continuing to blur between computing devices (laptop/tablets/phones/etc)... and that isn't taking much time at all.
