This seems like a great deal for people already with Virgin (Spit!).
Been searching for a dongle for my new NC10, and most are £15/month with 12 month contracts, or pay as you go at £2/day or £15/GB with £40 or so towards dongle.
£60 for the year including £25 Dongle - surely this is hot?!
Apparently £13/Month for M customers
