I have been using Box.net an online storage service for quite sometime and I think they are doing a real great job with what they are offering 1Gig Free storage and other storage plans starting from $4.99/mo for 5Gigs but its bit expensive at least in India and recently from an article about Live Drive it appears even Microsoft (Live Drive) & Google (GDrive) are also coming up with their own virtual online storage services so I think its going to be a bit of a competition for Box.net.
