I just read the MacMinute announcement regarding the about the new Sonnet Titanium G4 1.2MHz Upgrade (for 550 & 667MHz models). MacCentral announced this same thing last Sept. <br>http://www.macworld.com/news/2005/09/14/sonnet/index.php<br>Was there a problem with these upgrades when originally released? I never read anything negative about these upgrades but now I'm alittle curious about what happened.<br><br>
