Jakob Nielsen is making headlines this morning with this “usability findings” study that is highly critical of Amazon’s Kindle Fire. Nielsen, who’s been dubbed a “Web usability guru,” claims the new tablet offers a disappointingly poor usability experience due to a host of factors. When it comes to new tablets, though, I think we all suffer from a case of heightened expectations due to the fantastic iPad. The Kindle Fire is inferior to Apple’s tablet, to be sure, but it’s much smaller and much cheaper — so that should be no surprise. Other Kindle Fire reviews have been much more positive, and I think the device will find a big audience of consumers willing to sacrifice some performance and size for the more attractive price.
