Apple had a truly practical UMPC over ten years ago, far more so than the devices available today because the batteries lasted long enough to be genuinely useful. It was called the Newton. I still used mine until I misplaced it maybe 18 months ago because there still isn't any comparative product available. When it was still in production it was every bit as powerful as the desktop PCs of the day. Even the handwriting recognition worked well in the later models, and the UI was designed for the ground up for a pen interface making it much more usable than wince.

So, where is there anything on the market today that will run general office type applications along with your normal PDA type stuff in a format that is big enough to actually use but still small enough to carry and where the batteries will last all week (or even all day)? There isn't anything out there.

Thank you, Mr Jobs, for canceling Apple's last truly innovative and cutting edge product simply because you happened not to be at the helm when it was developed.
