No doubt iPad is worth replacing the conventional laptops. I had the bulky old HP Envy laptop and then saw iPad 12.9" in my friend's hands. Casually handled it and loved it so much when there was only reason worth considering is Battery backup but then again my Friend suggested to buy Laptop power banks from this research bloggers website: https://www.powerbanktalk.com/best-portable-laptop-charger-a...
Bought Anker power bank and This combination are best I have ever used. I can work on the go without worrying about charging and iPad is so flawless.
