my five euro-cents:
i'm not interested in specs, GHz, busses etc. i do have a more marketing/consumer/buyer point of view.
what correctly was said above: imac was/is a good start to get connected to the iNet, to have "a computer" at home. it's a all-in-one machine, no fuzz with "what else hardware do i need? can i connect such am monitor to this plug?? what plug????" - a friend of machine unpacked her new imac and within 3 (three) minutes she was online, everything was running...-
emac is very us-cenctric - we don't have colleges, computer-rooms, we still use ink and paper in old europe

no idea, wether there is any need for such a prodcut.
G5 is for pros - expandable, fast, reliable, state-of-the-art, a good 4 years investment.
iPod is - well, just great!

ahh, the year of laptop - very good idea! the all-in-one for the pros

again, no probs with "does it fit, what else do i need etc"
------
so, question 1) is the annual keynote of importance for the consumer?
No.
just for the press, the guys from the stock exchange
q2) is the keynote of any importance for the apple afficionado?
YES!

q3) is the 20th anni of any importance?
well, from a PR/marketing pov it is, or it should be...- but ol' steve said allready, for the superbowl itms is the main theme.
q4) does the market needs new products?
what is a NEW product? more GHz, front busses, ram chips...? no.- this is just for nerds, and as we could see in the last months, all the iBook updates etc are done very calm, unexited, "hey, buy the way, the iBook has a G4 instead of a G3 or whatever...."
-----
so, i think, there will be some updates, we will see new software (but this is of no importance for a journalist "apple has is own "office" - so what?? - the allways had their own stuff..."/it will be a revolution for the rest fo us, but not for public...-
a renaissance of the Cube? - "apple gives flop a second try"... no, i own a Cube, the best home-computer/digital hub ever!! - a headless mac maybe is the follow up of an emac...
no, IF 20th anni is important for apple, and IF itms is getting a little out of focus and IF we don't see the überG5 with 4x4GHz...- we will see a device, small & beautiful, easy to handle, plug-n-play. i'm sure, it has to do with pictures! mms/foto mobiles is a big trend over here...-
have you heard about the concept of a "life recorder", a storage device, so small and so big, to record literarly everything of your life? from sound to pics to moving images...? when i go to my clients, i like to "wear" a little usb-stick with all the files i need for working - just plug in, start working (windows/apple/anyhow)... imagine a much mightier solution, including my personalized system... no, no iPod, a little bigger (in Gigs), connectable to monitor, tv sets, stereos, whatever...-
so, in less words:
iWrite and the überiPod
