I hope to see the iMacs get better screens in the next rev later this year as one of the few things Apple can do to boost this machine uless they suddenly change the form factor (which I doubt).
I expect to see 17" with MacBook screen
20" doing what the 23" currently has.
I also expect to see the 17" get the larger graphics card option.
I wouldn't mind see lightscribe disk drives -or Blu Ray!
I hope the next ones get the new 802.11N wireless standard as well
Black models would also be an excellent move in the world of front row.
Better speakers for front row and games would be good - virtual 5.1 like most LCD TVs seem to have at the high end.
More ram, says 512MB/1GB on the logic board and 2 spare slots, would be most welcome.
HDMI out would rock. Or a real DVI out to reduce clutter and connections.
Digital TV tuner and aerial socket would be very nice.
BT Mighty Mouse to compliment it would be good.
OLED clock/multipurpose long screen under the chin of the chasis to display Widget like info.
Ah time for sleep with so much dreaming...
