FORTUNE -- On Sunday, Baird Equity's William Power lowered his Apple (AAPL) price target for the second time in four days. That got me wondering how often he changes his mind about the company.

A sampling of Wall Street's post-launch notes
Sales estimates: Most analysts were cautious, fearing perhaps that whatever they wrote would soon be overtaken by an Apple (AAPL) press release. Most, like Piper Jaffray's Gene Munster, stuck with 500,000 units. But Baird's William Power estimated that Apple sold "roughly 1 million" the first weekend, Wedbush's Scott Sutherland "wouldn't be surprised" by that number and Global Equities Trip Chowdhry thought Apple "may have MOREPhilip Elmer-DeWitt - Mar 14, 2011 10:52 AM ET
