I had 3g broadband for over a year now and i find it very good, some evenings it can be slow tho. I pay EUR19.99 per month. Had a few problems at the start but rang customer service (think they are in India aswell) and they solved the problem, even rang me back to check it was ok.
i dont download that much but when i do it is slow enough, but that doesnt bother me as i dont do it every day, just the odd movie.
I can watch Youtube, video clips no problem.
3g even rang me the other day to say because i was with them a year they are giving me 2 months for free, happy days! i told them that the connection is sometimes slow and she said they got some new contract to be the major broadband supplier in Ireland and that the coverage would get better.......
so im happy with 3g again it depends on your location..
