Who’s the target audience? Well, me for one.

A three-hour battery life will easily last the duration of my commutes on public transit to and from work and, with some care, most of my short-haul travel.

It’ll handle my middle-haul too with access to some kind of external power supply; rail travel, my preferred method, is providing power jacks and Wi-Fi for business travellers (and often for coach, too) and UMPCs will likely have some sort of car adaptor for the four-wheel types and extended batteries for the aerial guys.

The package is small enough to be easily usable in confined spaces (like, say, the seats of common carriers listed above) and taken as part of carry-on luggage without taking up much of the allowance; but it’s big enough to be easily used and easily read.

It’s also compatible with my home operating system and other software without emulation; indeed, I’m looking forward to having a full Office suite available whenever and wherever I like.

I don’t think I’m the only one with a list of wants like that.

“They now know what their target customer is.”

I would be willing to accept the entirety of your post if I could get myself to come to grips with this point. Have they really identified a target customer? Sure, I guess they are looking for the early adopters with lots of disposable cash. But how will they actually use this product? The marketing seems to sell the fact that you can use it anywhere. But what will I do with it? What are the capabilities that I will want to have access to that my laptop and my cell phone won’t let me have? (I’m not saying that there is definitely no use for Oragami, but I don’t think the makers have any idea of how to answer this question.)

The question of meeting the desired specifications for battery life and form factor and such is moot until the usage question is addressed. As is, I get the impression that the specs are arbitrary. It seems like people are just speculating that 2 hours isn’t long enough but 8 hours would be plenty. Without a context of how someone will use the thing though it is impossible to say. 2 hours might be plenty or 8 hours might be dreadfully inadequate.
