Considering you are restricted to 80 hours I can't see why they call it unlimited access (ditto BTOpenworld) - 'xcept for the play on words that is - AOL for their sins do give you unlimited access in the true sense of the expression - i.e. be online as much as you want over the month (with a 2 hour session limitation). I would check what they charge if you go over the 80 hour limit - and can you check your usage time as you go along to ensure you stay within the limit?
Otherwise looks good to me.
