Unisys Corp is expected on Wednesday to unveil what the Wall Street Journal calls a breakthrough in tiny computer, cramming an processor able to run all A series mainframe software into a ceramic part that measures 2 by 2: Ulric Weil at Weil & Associates said the machine would be a breakthrough – nobody has anything like this, although he expects that other companies will follow with similarly miniature machines later this year; the paper quotes industry executives saying that the desktop machine will be faster than the present bottom-of-the-line A1, but cost $40,000 against the A1’s $100,000.
