Are there actually that many uncapped services in the UK?

I am thinking of switching my internet connection to F9's cheaper package which allows just about 2GB for £10 a month and then just pay the extra 75p/GB if I need any more. I have hardly used the internet for anything other than looking at 2 or 3 forums, IRC and email and my usage rarly exeeds 2GB. No point in paying for what you don't use.
