my two cents.....
.... i doubt jobsey would announce a new powermac and then tell us we have to wait until December for it to ship (some poster earlier flagged this). unless the current line-up was slashed in price by about 50%, no-one would buy a new mac until the revision shipped.
surely Apple has learnt that the second generation of any of their products is more eagerly awaited than the initial release. myself, i don't buy the first release of anything Apple (or microsloth, or Nikon or anything with a silicon chip in), be it hardware or software. i've always waited for the first update before making my decision (then buying the older gear if discounts make it attractivly enough cheaper).
i predict the first batch of the new G5's will sell out very quickly, apple needs to get their sheisse together and make sure they have enough stock of the new machines.
i am using some extremely ordinary celerons in my business at the moment which are in dire need of an update, if i have to wait for availability, i'll wait. while these machines cost me a fortune in downtime (20+ crashes & over 12 hours wasted last production day), i'd rather wait and see whats coming. i already have my order (for two duallies, whatever the one below the top-of-the-line mac is) in at the local supplier, if there are delivery delays, i'll just demand (and get, i love the Consumer Affairs Tribunal) an extra gig of memory in each machine for each month (or part thereof) i have to wait.
don't let me down stevie, announce some nice toys and make sure you can ship them. 😉
