The main reason for those heaters is not to keep the screens from getting damaged, but rather to keep them working throughout the cold. They can suffer from low-contrast, low refresh, even just plain not working if the temperature falls too much (but would resume working fine once warmed back up).
I'd check what the manufacturer says the operating temperature is, as long as you're within that range I wouldn't worry. Even below the minimum temp, most likely it just wouldn't work perfectly until warmed up. I've left various devices with lcd screens in the car (cellphones, PocketPC, etc.) and no problems yet. Then again we're in TN, our winters aren't quite as brutal as farther north.
