As these new forms of Display devices are created, first as just lines of LCD text, now whole screens. All they are is a display device. The PAD is no computer, some have tried to make full fledged PC computers out of them, i.e. HP. It will be years before they are ever able to mussle up the power of a 60's main frame as Desktops did back in the late 80's. To have the power of a Cray One super computer, I have close to that with what I use now a Quad Core AMD 64 running at 3 gigahertz. And it's ATI 2560x1600 max screen is as good as most 70's film studios did (i.e Star Wars). I-MAX is still beyond most these days.

In time things will get there, I started out with a Atari 800 in 1980 and that was a 8bit computer with a 352x240x256 colors and 4 8bit sound channels into one mono audio out. Compared to my now 7.1Dolby surround sound in 32bits per channel. and all for under $400 two months ago, and with a newly added Sound Blater PCIx card and a $600 e-SATA 8Tera RAID external Hard drive to add to it's internal 1Tera boot drive. With taxes added it is still under $1,200, some tablet systems are near that cost. And that is not even going into Cloud memory or storage space that may make tablets equall to 1980's PC's.
