Part of this is down to the general economy getting better, and settling down after the knocks of earlier in this decade. As a result, IT budgets are up 3.4 % this year. Furthermore, due to the recent boom-and-bust cycle's "echo effect," we could see technology spending going up by 12 or even 13 % this year. This is a great contrast to the decline in IT spending earlier in this decade, which happened for the first time in nearly 50 years.
A lot of spending this year and in the next is expected to be in replacing infrastructure. And although tech vendors should not see this a return to the boom of the late 90s, we are definately seeing a recovery.
