Software was a top performer for the vendor. HP Software revenue doubled over the prior-year period to $698 million, led by strong growth from the businesses acquired in HP's purchase of Mercury Interactive.

"I think on software, we gave a range a year ago of getting the software business to look like what a scaled software business ought to look like, and we gave ranges in '08 of roughly 18 percent to 22 percent, and we've done nothing to change that view," Mark Hurd, HP chairman and CEO, said in a conference call. "We believe that the software business has done a nice job integrating Mercury as well as several other acquisitions during the year; it wasn't just Mercury. They've also done a nice job organically of building up our organic capabilities at the same time as we've been doing some integration. So we feel real good about the operationalization of all of that and I think you'll see that platform that I described with the Mercury integration generating the kind of profit levels that we describe."

The vendor was buoyed by its notebook revenue, which grew 49 percent over the prior year period. However, desktops showed only a 15 percent growth.
