Former Vice President Dick Cheney is a changed man, sort of.

President George W. Bush's right-hand man has a battery-powered heart, and uses a BlackBerry and Kindle.

"I didn't have even a cell phone in the White House," Cheney admitted in an interview with NBC's "Today" show.

Cheney, however, remains a die-hard Republican who thinks President Obama will get booted from office in 2012 because he overestimated the public's support for health care reform.

"I think he'll be a one term President," Cheney said.

He added that President Obama now understands that the Bush administration's war on terror was the right course of action in the years following the 9/11 terrorist attacks.

Critics have blasted Cheney's support for harsh interrogation tactics, such as waterboarding, for suspected terrorists.

"I think he's learned that what we did was far more appropriate than he ever gave us credit for while he was a candidate," Cheney said of Obama.

Cheney declined to say who he thought would unseat President Obama in two years, but called former Alaska Gov. Sarah Palin "interesting" and praised her reality show as "very good."

"She's clearly a factor within the Republican Party," Cheney said.

As for his relationship with Bush, Cheney said it is "pretty good."

Cheney noted that his upcoming memoir will detail some of the differences the two men had.

"I have a bit of the sense that I'll have the last word," Cheney said.

He admitted that Bush considered dropping him from the ticket in 2004 and even offered to step down as vice president three times because of his controversial image.

Bush released his memoir, "Decision Points," last fall.

Cheney, who turns 70 later this month, has not decided whether he will get a heart transplant. He suffered his fifth heart attack last February.

For now, he is outfitted with a battery-powered heart pump.

"It's a wondrous device," Cheney said. "I'm here today because we have that technology."
