Customers of Hewlett-Packard and Electronic Data Systems offered a range of reactions Tuesday to HP's US$13.9 billion bid for the massive outsourcing company.

HP will benefit from EDS' talent pool, but the specter of layoffs -- which EDS President and CEO Ronald A. Rittenmeyer indicated Tuesday would be possible as the companies integrate -- raises concerns about customers' existing deals, said Nina Buik, president of Encompass, an HP user group that says it has 50,000 members.

"From a business perspective, I understand when you consolidate staff there's going to be duplicate jobs," Buik said. "I want to make sure the customers are still getting the level of service they signed up for. That would be my concern."

HP's pending purchase, which will bring it in close competition with services leader IBM, has been approved by both companies' boards of directors, and is expected to close in the second half of this year.

The deal will result in a new unit called "EDS -- an HP company," based in Plano, Texas, where EDS has its headquarters. Rittenmeyer will lead the new unit and report to HP CEO Mark Hurd.

Joe Lovetere, president of Hub Technical Services, said he was surprised by HP's move, but called it "exciting" and not likely to be a threat for his South Easton, Massachusetts, company, which resells HP's hardware and provides services.

"I don't think that it affects our business in terms of the market segment we have," he said, explaining that it is divided between the public sector and small to medium-size companies. EDS goes after the biggest accounts, Lovetere said.

One of those is Xerox, which has spent billions of dollars on EDS services during the past couple of decades. The company signed a US$263 million deal in April that will see EDS manage and support its end-users, service desk and mainframe operations. It was a recent milestone in a long relationship.

Xerox's latest deal with EDS provides it with "flexibility in the event of changing business circumstances," and the pending acquisition could well qualify as such, said Carl Langsenkamp, director of public relations at Xerox.

However, he declined to speculate on whether Xerox would, in fact, look to alter the contract.

The company has a "two-fold relationship" with EDS, partnering with it as a member of EDS' Agility Alliance, which brings together offerings from a range of vendors into an "agile enterprise platform," he said.

Meanwhile, HP and Xerox compete in the office printing business, but Langsenkamp downplayed the potential impact. "This move seems to retrench them in IT outsourcing, but not document management," he said.

HP's hardware division presents another potential wild card for customers, should HP attempt to move EDS clients over to its computing platforms.

Hurd insisted during a conference call Tuesday that EDS would resist such an obvious temptation and remain hardware-agnostic.
