Drop is good, it helps spread the existing bitcoin to new people which is desperately needed if bitcoin is going to be adopted and used by the masses.
I'd like to see it drop down to $200 USD. That will get a lot of holders to sell and distribute the currency to people who will actually use it for commerce.
Agreed. A price drop around a time like this (with Dell announcing their acceptance of the currency) will help make it more accessible to new users. People tend to look at volume over value, so I can see how some may stay away from Bitcoin when they hear $20 will only get them a fraction of a coin.
