In possibly one of the more ambitious outlooks for Mac market-share increases, Gartner is forecasting that Apple will double its market-share in the US and Western Europe by 2011. The reason for the dramatic increase is said to be two-fold: Apple continues to do well in its Macintosh unit and competitors aren't meeting Apple's competitive pressure.
Apple is challenging its competitors with software integration that provides ease of use and flexibility; continuous and more frequent innovation in hardware and software; and an ecosystem that focuses on interoperability across multiple devices (such as iPod and iMac cross-selling).
Gartner also predicts that by 2012, 50% of traveling workers will use devices other than notebooks. Gartner cites new "Internet-centric pocketable devices at the sub-$400 level" as a primary threat to the notebook in this arena. Notably, the iPhone fits this description.
