2011 is supposed to be ‘the year of the tablet’ and while growth has exploded since 2009 it hasn’t really affected web design, but all that may soon change.
In the same way ebook readers are changing the way books are produced, tablet PCs may change the way web site content is produced. For example, how would a web site be designed differently if it were meant to be touched instead of clicked? We already have separate domains and style sheets for mobile phones, why not for other mobile devices?
Web analytics are currently smart enough to detect browser types, but how will we detect tablet PCs. There are so many different types that we need a tablet comparison just to know what tablet runs what operating system for compatibility!
Maybe it won’t be a problem. Hopefully it will all work out, but as technology progresses, so must web design.
