Thanks for the link.
Does this logic work for PowerBooks? i never understood the whole rev a-e or whatever they had.
As mentioned, week number resets every year. Common convention is that weeks start on Monday, and 'week 1' starts on the first Monday in January. (So, for example, this year had January 1st on Sunday, so it was technically part of week 52 of 2005, while week 1 of 2006 started on January 2nd.)
The whole rev a-e thing is when they made an update to the computer. So a 'rev a' computer means it is the first iteration of that model. The just-released Mac Pro would be a 'rev a'. The mini, iMac, and MacBook are all in 'rev a'. The 15" MacBook Pro is currently in 'rev b' because they boosted the processor speeds, while the 17" MacBook Pro is still 'rev a'.
There were five revisions of the Aluminum PowerBooks, so they are labeled 'rev a', 'rev b', etc. (Some models get more descriptive revisions, like the Titanium PowerBook G4, which had 'DVI', 'SuperDrive', etc. Sometimes people also refer to the revision by its top speed, so the Power Mac G5s could be called 'G5 (2 GHz,)' 'G5 (2.7 GHz,)' and 'G5 (Quad)'. (The quad getting a descriptive identifier.) Apple usually refers to them by release date. For example, the education-only iMac Core Duo (with integrated graphics and a Combo Drive,) is officially 'iMac (mid-2006)' where the consumer model is 'iMac (early 2006)'.
Yes, it can be confusing. Check out
