Yes, it is tempting to work on the laptop while you drive, sometimes you just have to multitask but please refrain or this might happen:

The California Highway Patrol says a deadly head-on crash north of Sacramento was likely caused by a man at the wheel working on his laptop computer.
[…]
One driver told CHP investigators he swerved and avoided the Toyota, which then struck an oncoming Hummer. The couple in the Hummer was treated and released for minor injuries but the Toyota driver was pronounced dead at the scene, police said.
“We have reason to believe he was operating his laptop because it was still on and plugged into the cigarette lighter,” said CHP Cmdr. Scott Silsbee.

A Toyota doesn’t stand a chance against a Hummer.
When you read something like this it really makes you think, was what he was doing on the computer worth his life? This is a good wake up call for me because I’m not the must careful driver when I’m messing with my palm TX looking for something to listen to.
