4G vs. Wifi - is it too early to declare a winner?

I'm a highly mobile worker. When away from my home office, which has fibre broadband and ubiquitous wifi coverage, or one of our office locations with wifi and LAN, I use public wifi and hotel LAN services through our Business Everywhere Smart offer. 

However, I find that most of the time my HSDPA+ connection is fast enough (when doing email, light web browsing etc.). Now that I have an effective 'all you can eat' data plan when in my home country I find myself using public wifi less, usually only when connecting to my virtual desktop or for video and other real time communications.

Now that 4G covers most of the locations I visit in the UK and most of the other cities around the world (at least for EE users in the UK) I can see that the main reason for keeping wifi is cost control when roaming rather than for the user experience.

I'm interested in the opinions of the readers of this blog, will 4G replace wifi?
