Revolutionary
Take a look at what Apple has pioneered in the way of Desktops:
(1) All-in-one design
The original Macs were an all in one unit - simple, clean, compact
(2) Consumers demanded choice
Then consumers wanted to choose their display size and resolution, especially designers, so they split them up a la the PC industry (and then they could use PC compatible displays at a lower price)
(3) The i's have it
Then the iMac came along and joined the two at the chassis again.
(4) But wait, I missed one
But does anyone recall the 20th Anniversary Mac? Five years and a day ago, the $10,000 PC had a then industry leading flatscreen with built in speakers and CD-ROM that was connected via a proprietary cable (could Gigawire serve this purpose) to what I will call a 'command module' that housed the CPU, HD, etc.
(5) The next generation
So perhaps the next generation 'iMac' replacement in the product line will be such a device. I believe all components will be housed in one unit, not two like five years ago, but this would be a revolutionary move for the industry. Gateway couldn't make it happen (even with placement on TV shows liek ER), perhaps Apple can.
