This is would definately sell millions and I for one would buy two of them! There are millions whom just want a touch type keyboard pocket laptop and so far there has not been one made yet. This is a great design if it becomes reality.

I do not find any of the existing UMPC's or MIDS very functional as they do not provide a touch type keyboard in a pocketable size. Carrying a foldable keyboard is NOT practical as those are just as large as the computer and having it integrated is what I want. I think this is a great design and it would appeal to millions of business users unlike any slate, etc.

Finally someone realizes that there is a huge demand for a pocket laptop that provides a good touch type keyboard. I think the concept is great and would definately buy one if they ever make it a reality. While I think this would be the ideal design a simple clamshell that copies the old Psion 5mx could be created right now with no new technology other than stuffing the same internals that smaller full PC's have created such as OQO, Wibrain and others. A clamshell can provide a usable touch type keyboard most could type about 80% of desktop speeds. I would love to have the dragonfly computer but if it is delayed due to technology needed to be created a simple clamshell could be an alternative any computer company could create fast and put on the market.

It is not the price but the size and shape that really is the problem. How do most people use a full Windows computer? it is not with their thumbs and that is the key issue. Since most people do not find it ideal nor comfortable to much input with their thumbs then most OQO owners probably have multiple computers. People do want a pocket laptop but most would want it to just work the same way as a normal computer so that means touch type input and they are likely not to own another computer.

That is why price then comes into the picture as it is expensive for something that does not have the expected input method people would expect for their sole computer.

This design has been unchanged in shape and size and it sells somewhere between 8-15 thousand units a year; that is pretty weak. They should add a second model that is about 7″ to 7.5″ long by 4″ to 4.3″ wide and about 1″ or less in height; that would provide the size needed for a good keyboard. Yes a small handheld if designed right can provide good input. Remember the Psion 5mx at only 6.9″ by 3.6″ I could type about 80% of desktop as the keys were large and easy to type on.

After 8 years and they still can not understand that their thumb input is why very few people want to buy an OQO. Now they add an Atom processor, wow, that is going to change my desire to thumb input, NOT!

I predict OQO will fail if they keep this kind of weak innovation. They need to turn their technology into a true pocket laptop. Make it a little longer so that it can have space for a true touch type keyboard. Get with the times and use a touch screen which will eliminate the scroller space and give more room for the keyboard. Use flash memory since their hard drive is so noisey and runs so hot. Then the thing might start generating some real sales. A thumb input is fine for a phone but is just plain lame for a full blown PC; it makes it a toy not a tool.

This is the best UIMPC so far! Finally a jacket pocket size UMPC that is both a clamshell and slider! fyi, Pocketables.net has some great initial tests on it; they have a 14 minute video showing it runs Vista with no problems, with 10 web pages at once, and also 4 programs with no issues at all! They are waiting to do a complete review when the 4-5 hour extended battery arrives.

I am waiting for that review too as I would buy one as long as the battery does in fact last 4 hours!

Pocketables.net has a 14 minute video showing the D4 does run Vista with no problems! Remember this review above was the prototype not the final released product that Sharp is selling now!

I think it is the best UMPC so far! Hopefully more companies will copy and build upon this great design. Yes I loved the HPC Windows CE too but for me I would rather have a full windows computer in my pocket as I have to run business applications that you can only run on desktop MS OS.

an

Conics and several other companies are selling the D4 and installing English Vista. There is an extended battery that is a must to increase the battery life to 4-5 hours. This is the first UMPC that might be a practical computer not just a toy for the geek at heart. Business users just want a touch type keyboard, pocket laptop that runs full Windows and here is the first such device. I hope more companies start copying this form factor.

Even though the cell phone capabilities do not work outside of Japan, the form factor alone is worth it. The wifi and computer functionality form factor is worth the price.

I hope Voom wins the lawsuit! especially when dish clearly manipulates the truth. They claim to be the leaders in HD, they claim to have added 22 new HD bringing their total to 80 HD. That is all false marketing hype twisting the truth. Here is the truth they only have about 40 HD as many channels are duplicated on 2-4 channels. There are only 7 new channels as they fail to mention they removed the 15 Voom HD. Most of their HD lineup is up converted and not true HD. Their picture quality has gone down. Here are a couple examples of the new channels, the weather channel and the cartoon network; come on dish whom even cares about those and there is no real difference in seeing those in HD? I'm going to cancel dish next month!
