Despite predictions that it would sell out within hours, according to this Computerworld article the iPad didn’t sell out on its first day.
Granted the sales numbers were still quite impressive, and for some people the device is a great synergy of Apple’s ease of use and a media centered tablet device. However with its locked down approach limiting its usefulness in several areas including productivity applications, it probably won’t fully replace any of the devices most technophiles already have. It looks like several other manufacturers will be putting out similar devices this year. It will be interesting to see what they do now that Apple has broken the ice.
