Windows Tablets Fail
Apple and Amazon so far are the only two companies that have been able to get the tablet computing space correct. Microsoft made significant strides in 2011 when it announced that its newest version of Windows, Windows 8, would run on ARM-based chips, and thus be tablet friendly.
But with companies like Hewlett Packard (HPQ - Get Report), Acer, and Lenovo potentially leaving the tablet market because demand hasn't materialized, Windows-based tablets will be a commercial flop, despite getting good reviews.
Apps Fall Out of Favor
Smart phones have become so popular in part because of "apps" but the presence of HTML5 will really take form in 2012. HTML5 is the language for showcasing information on the web, and as companies like Microsoft, Apple, and others begin to integrate HTML5 into their software, apps could become a thing of the past.
