Indeed, today if you want a phone that isn't gigantic the options are really limited. Zenfone also had benefit of being quite sturdy since the back wasn't made from glass/metal, so you can go without a protective case. I have dropped mine a couple of times, but it hasn't suffered any damage until now.
