Has there ever been a time that Apple has announced a redesigned computer (not new) and not sold it near immediately? I'm trying to get a feel for how long I'm gonna have to wait between announcement and shipping of the new MacBooks if they are announced within the next couple of weeks... Is it wishful thinking that these things will be released immediately or within a week of announcement?
Yeah, shipping within a week is wishful thinking. On an Updated product, I think the lag is generally a few weeks (2 at least). New products can take much longer- as I said before, my 17in MBP (1st gen) took around 4 months before it was SHIPPED.
If you have a real need for new hardware, the only reasons to delay are: 1) to see if the updates are worth the wait or 2) take advantage of price drops on the existing line.
I'm in camp #2, since I don't really do anything that requires cutting edge technology. On the other hand, I have a hard time forking over good cash for something that will be cheaper (or better for the same price) in a month.
