Yea...I just noticed it too.
BUT...I kind of think that it should be more...because between Feb 4th 2003 & Sep 8th 2003, there was only 71 days between each update, but it wasn't really a update since they only added a 20" model and all the other models stayed the same....so that 21 days "skewed" the average update dates.
I was just calculating the average again between the dates without the 71 days and I got the average to be 224 days.
Also, I calculated the average update releases without the 71 days (from 02/04/03 to 09/08/03) and the 90 days (from 10/12/05 to 01/12/06) since the both also skewed the average...and I got an average of 247 days between updates... so the update seems to most likely be between May & June..as some MR users think.
***Note: I didn't add the 90 days between 10/12/05 & 01/12/06 because the average between every other update was 162, 216, 239, 245, 287, & 335 days. So obviously 71 days and 90 days would bring the average much much lower than it should be.***
I was taking the averages about 30 minutes ago because I was seriously thinking about buying an iMac today...call me nerdy/geeky/turd...yes.
I hope people can understand what I did. haha
