You're lucky. I'm an IT consultant and travel every week. I need my laptop for work. At home, I have a fairly new desktop I don't even use, but if I did not have to travel, maybe I could get by without one.
The worst part is I like to do workout DVDs in my hotel room. I can fully charge my laptop before I leave the office, shut it down completely and head back to the hotel. Change into my workout gear(mind you, the max time is 2hrs, but 1 hr is more realistic), get the tv all ready to go and the minute I hit power on the laptop, it says the battery is dead. Then I curse the heavens for not having my charger in my bag while I head down to the hotel gym.
It will be so nice to have a laptop that lasts more than 2 hours on a charge and not sometimes sound like a plane is about to take off.
