Driver updates are only super easy if the driver exists. It's impossible for me to update my keyboard driver as the latest Apple driver for my MBP is buggy, and no one besides Apple makes a MBP keyboard!
If you're talking about other drivers, that's not quite true. The only laptop graphics card I've had problems updating is the ATI+Intel combo (due to ATI only having vendor specific drivers ATM). Every other laptop I've worked on not only is easy to upgrade drivers, but they're usually updated automatically via Windows update.
When you install windows you lose GPU switching - it is not an option with Apple's drivers or anyone else's. The link I posted requires about 1 min of reading a 10 min of work. I guess that is too much work for you?
