George Ostrogosky wrote a very high quality history of Byzantium, but many of his conclusions have been questioned or superceded in the decades since. The most recent and up-to-date survey is Warren Treadgold's History of the Byzantine State and Society.
On page 709, he states:
From what I've read in several sources (including this one), the cannon had a notable impact (no pun intended!), but not a decisive one. Although the way the siege eventually ended was not terribly impressive, it was only a matter of time given the 80,000 men Mehmed II had, and the external aid Constantine XI didn't have. A Byzantine comeback in the chaos after 1402 or even as late as the 1440s (with various civil wars and Hungarian invasions) would have been plausible, but not in 1453.
Why are people arguing about the quality of the Byzantine army? I'm a Byzantium Booster (tm), but the Byzantine army hadn't had a success worth writing home about since the 12th century.
As an aside, the Emperors did NOT have an unlimited supply of money; if they had, they would have been able to make the other half of the payments owed to the Venetians in the 4th Crusade, and things would not have escalated/degenerated (depending on your point of view) so much.
edit: For those who consider Treadgold suspect, Steven Runciman has this to say on page 85 of The Fall of Constantinople, 1453:

On page 709, he states:
Early in 1453, seven hundred Genoese and three hundred Venetians arrived, bringing the total number of soldiers in Constantinople to some three thousand foreigners and five thousand Byzantines ...
Since the Turkish cannons could only fire at intervals, and the giant one could fire just seven times a day, the Byzantines were able to patch up much of the damage to the walls as it was done ...

At the end of March, when the Turkish army was moving through Thrace, Constantine sent for his secretary Phrantzes and told him to make a census of all the men in the city, including monks, who were capable of bearing arms. When Phrantzes added up the lists he found that there were only four thousand, nine hundred and eighty-three available Greeks and slightly under two thousand foreigners. Constantine was appalled by the figure and charged Phrantzes not to publich it. But Italian witnesses came to a similar conclusion.
