"These days, dictators have a lot more tools at their disposal than the ancient and medieval monarchs, yet they are wimps when compared to them. Those monarchs did not put up with nonsense, yet they accomplished what Mubarek can not with swords and clubs. Seriously, wtf?"
Medieval monarchs were, in Western Europe, always forced to compromise. This is why the magna carta was signed. Or, even worse for the monarch, Mary of Burgundy was forced to sign "Het Groot Privilegie" (in english: the great privilege), wich instantly granted cities privileges that were comparable to those of the Italian city-states.
Another clear case is this: When Charles the good, count of Flanders was murdered, the french king (whom Flanders belonged to) couldn't get his candidate elected. The people preferred a different candidate and that one got the position fairly easy.
Absolute monarchs are something of a more recent time. They fit better in the period of the 17th to 19th century. Although, there too, that system shows clear cracks. You mentioned Napoleon, but he himself is the result of a civil uprising. In the end, most (if not all) absolute monarchs were dependent on how well their people fared.
Mubarak doesn't seem to have all control over his army anymore. And when you shoot into a crowd of over a million, it's the fastest way to find your death. 
God: Behold ye angels, I have created the ass.. Throughout the ages to come men and women shall grab hold of these and shout my name...
