If the extra features on a phone are not used they will not drain the battery, the gas used in the truck will be the same regardless if the bed is used or not. 🙂
I'd rather buy something with the features I need today all wrapped up in a nice UI than something that's a bit of a mess but has extra features that I may or may not need one day.
Plus it integrates with my PC and iPad 😀
To each their own. Nobody will ever be convinced away from what THEY like, so these analogies and discussions are largely pointless 😛
