The top photo has some promise to it.
IMHO, the OQO Model 02 and the Sharp MM20 both epitomize the ultra-portable concept in that they both dock and are not desktop replacements.
The OQO Model 02 does it by having a cradle with an optical drive that you place it in, which then allows it to be connected to an external keyboard, mouse, and display. When you need to leave the office, you just undock your OQO and off you go. All your files are there (with the exception of any external drive files).
The Sharp MM20 does it in similar fashion, but you close it up to place it in the cradle. The cradle is connected to your main computer and the MM20's hard drive shows up on your main computer which allows use of the files on the MM20's hard drive. So if you have all your work files on your MM20, then it is the same as the OQO, you just undock and off you go.
The advantage of the MM20, is that you are really using a desktop machine when you are connected. So you get the full capabilities of a desktop system. Where as with the OQO, when in cradle mode, you are still using the OQO to run the system.
My guess is that Apple is going to pursue the MM20 style concept and use FW in target mode to connect (dock) it if they go that route.
Apple will want a fully functional ultra-portable. What does Apple believe to be a fully functional ultra-portable? That is the 64 dollar question for sure.
This reminds me of the introduction of the iMac. From what I understand, SJ did not make the decision to not include a floppy drive until very close to it's introduction. The inside of the original iMac is hacked together more than any Mac I have every seen and indicates this to be true. I remember all the complaints about not having a floppy drive, and what was Apple thinking. Yet today, how many PCs, desktop or laptop, do you see a floppy drive as standard? Not many. Apple was definitely ahead of the market that time.
Apple also surprised the Mac community when they switched to Intel. The decision was made at the very last minute before the MWSF a couple of years ago. At first everyone thought, oh great, another CPU change like we haven't been through this before. How long is this going to take? When will it be available? And then SJ towards the end of the presentation showed everyone that what he was demoing was done on an Intel Mac. Totally surprising the crowd. Very cool.
And of course for those of us who were around when Apple introduced the first Powerbooks with the trackball in front of the keyboard. Another first that was adopted by the industry -- thankfully.
With the ultra-portable, I see Apple may do the same thing and surprise all of us. The iPhone and iPod Touch have great new multi-touch interfaces. Apple has been known to create excellent laptops and other portable devices. On a side note, the Airport Express still amazes me. Anyhow, daily I get to see my Apple laptop beside Sony and other brands. You can see an inherent difference and approach with Apple. I bet the ultra-portable will be no exception. My best is that we will see Apple crossing some new boundaries with it.
