The question of if a dreadnought could hover in atmosphere like that is moot. The real question is why the hell an experienced captain commanding one of the System Alliance's few capital warships decide to bring it down in atmosphere, right in the middle of a city, and then slug it out with a reaper head on?
As for the claim that a single hit from a reaper could destroy a dreadnought, clearly their lethality was overstated. If reapers could kill any warship like that there would simply be no chance to defeat them.
The bigger question is how the hell did the reapers destroy what could possibly be upwards of 50% of the Systems Alliance Navy in seconds. Quickly enough where Hackett or somebody couldn't send message down stating the obvious "we are getting our asses kicked". Even for the reapers that whole sequence of events moved too fast IMHO. Moving from the edge of the solar system, destroying a large fleet, and starting to vaporize some random city has got to take more than three minutes.
Even without comms from Hackett how could this naval station/military base/wherever Shepard was on the ground have no idea what's going on in orbit and in the immediate space around Earth. If they don't have the slightest idea of what's going on in this massive battle above them, how the hell can the Systems Alliance do simple air control duties and track the routine movements of hundreds of cargo, passenger, and military ships?
Maybe the battle took place farther out from Earth, but the cutscene at the start of the demo made it looked like the fleet was assembled damn close.
Conclusion: The Systems Alliance is incompetent. Senior commanders who made minimum preperations almost shat themselves before the reapers crushed them with their own oversized desk.
