Not being a user yet (still waiting on 5S? 6?) I can't fully answer, but in my area 3G is like (early) 1990's era dial up connectivity, so LTE might allow relatively painless web surfing.
I don't use mobile while away from home as an entertainment device, rather for web, email, etc. The only data intensive app I use while moving around is Bloomberg Radio for 20 minutes a day.
I do use mobile for entertainment (Netflix, YouTube, etc.) when home and in WiFi range.
