I have used Onspeed for about the last 11 months; It's got a lot better in the last few months with a software change. General surfing is much improved, some degradation of images is noticeable if quality is set too low. Happily this is something you can adjust easily.
There is no change in file download speeds, but; if Broadband is not an option I would say it's probably worthwhile.
However, it doesn't work with Mozilla Firefox. But, It does work great with Avant Browser.. Very fast front end tabbed browser using IE engine.
It's definitely quicker than IE or Firefox.
