My feeling is how can they deliver "Unlimited" disk space etc, its not possible, until "unlimited" storage is even possible
Offering "Unlimited and Unmetered bandwidth or space" is nothing but pure cheating. Just look the plans of hostgator; hostgator offers Unlimited bandwidth in one of their shared hosting accounts for $7.95 again they are offering only 250GB bandwidth with their reseller hosting package only for $24.95 . You got my point.
