Still waiting on my upgrade (West Mids and we're at the bottom of the list
) but would honestly prefer more upload than the additional download we keep being given.
I haven't noticed any speed issues - perhaps that's because we've not been upgraded yet, or mebbe the people in my immediate area don't abuse it
I have a problem with paying for a service then being told I can only use part of it - which to me is what capping is about. You don't buy a car and then get told you can only drive xx miles a day/month (then again, I have a serious problem with the proposals for road pricing - which is prolly on another topic somewhere).
There is only so much people will want to download, they will just get the information quicker.
