Well I eventually went for it. Basically 4G provides with faster downloads and uploads and will cause you to use a lot more data than you did under 3G. When you are in a 4G area you soon become used to fast response times which under 3G could take an age especially media rich web pages.
Youtube under 3G was always good , so I dont notice musch difference under 4G , but BBC iPlayer was virtually unusable on 3G , but on 4G becomes a very good media delivery channel.
I was going to do a series of posts of my experience with 4G and this is the first . EE have given (well sold) me a a LTE enabled Samsung Note 2 , and it's an impressive device. I used my original Note to watch Cockneys vs Zombies , I see the new device with 4G being used to watch a lot more.
Today I am going down to London so I will see how it fares , when I get down there I am going to tether it with my iPad to see if that's a viable opyion. I have a monthly data allowance of 10 Gb , I have a feeling i this brave new data world that may not be enough.
To paraphrase Robert Shaw in Spielberg's Jaws :
"We're gonna need a bigger data allowance"
