Re: people shown they like app(lication)s, not browsers
Yes, you can spot them easily. They are the ones that took more than others to start, and don't have a native UI. The Vodafone app I use is one those, but being one I use seldom, I may not care.
A web application can be great for simpler interactions you don't use often. It could be a curse for more complex interactions you need often.
