In the end, everyone recognizes that smallest computer can be best designed in cellphone form factor. The shear small size of cellphones can be manufactured cheapest, by using layers of thin material stacked. The wire length will be the shortest for data transfer speed. The data transmission has to be edgeQAM for multiple channels. And data compression has to be 1x8 pixels to compress ascii codes.

Having said that, the hardware can be using the latest lithography for finest linewidth. The cpu and largest L2 cache at the same clock speed can be impressive. USB bus only, will simply design for data storage. Keyboard can be a mere mouse roller and clicker?

Software development of Prex(http: connection) is still very much usable with pixel transmission of multimedia. The LCD resolution can be also very desirable if linewidth is improved. Cellphones already have camera and audio output. It just needs large data storage device thru USB ports. Printing of data can be done using drugstores or offices; just like online on-demand websites for applications.

It may take a few years for telcos to wake up with the advanced design; already in pieces that had to be just consolidated.
