The Apple iPad and the media-tablet market it has given rise to continue to affect the larger tech world.

Market research firm Gartner, since deciding to add media tablets to its worldwide IT spending projections, has raised its outlook for 2011. The firm now expects IT spending in 2011 to reach $3.6 trillion—a 5.6 percent increase from 2010’s $3.4 trillion, and a bump up from its earlier 5.1 percent growth estimate.

Gartner’s IT hardware spending estimates have also been increased from 7.5 percent to 9.5 percent in 2011. Additionally, worldwide spending on tablets alone is expected to reach $29.4 billion this year, up from 2010’s $9.6 billion. Spending on tablets is expected to average a growth rate of 52 percent through 2015.

"The addition of media tablets, reinforced by an expected additional decline in the value of the dollar, accounts for the increase in top-line growth,” Richard Gordon, research vice president at Gartner, said in a March 30 statement. “Absent the addition of media tablets, the forecast would have slightly declined in constant-dollar terms; however, with their addition, there’s virtually no change in the underlying forecast growth at the level of overall IT.”

This is maybe where Apple CEO Steve Jobs deserves a tip of the hat for turning just about everyone on to a device that just about no one thought they needed. Reviewing the original Pad in the Wall Street Journal in 2010, Walter Mossberg wrote that, while undeniably attractive, the iPad would need to prove itself a workable replacement for a laptop or netbook for common tasks. This, he added, "may not be easy, because previous tablet computers have failed to catch on in the mass market, and the iPad lacks some of the features … that most laptop or netbook users have come to expect." While it may not have been easy, Apple certainly made it look easy, selling more than a million in less than a month.

The Gartner report added that worldwide IT spending on software, which totaled $237 billion in 2010, is expected to increase to $255 billion in 2011; spending on IT services is expected to rise from $785 billion to $824 billion; and telecom expenses are forecast to increase from 2010’s $2.01 trillion to $2.11 trillion.
