We're still missing a slew of details, such as storage and launch dates, although we might not have to wait long at all to know -- if the claims are correct, one or both of the ATIV models may show their faces at Samsung's IFA 2012 events.
But if power supplies were standard parts that could be used interchangeably among devices (servers, switches, storage arrays, etc.) and swapped out at will, there would be no need to wait.
