Nero says where he comes from, the Narada is a simple mining vessel. 
What the hell kind of mining vessel is that huge thing? Have we ever seen something so huge used by civilians in any culture from the 24th century? Yes I know the allegory that perhaps a well armed tug boat ship from 2009 can do battle with ships from 1880, and it to make it ironic that the mid 23rd century Starfleet is horribly outgunned by a regular blue collar joe Romulan and his raggedy ship from Picard's time...but that thing is ridiculous in size and weaponry.
It looks significantly larger then the Enterprise D and Enterprise E, neither of which look like they could take out the Narada. Even with quantum torpedoes.
