It's not really a pocketable phone. Even in my sweatpants (trendy!) it proved so heavy it ended up dragging them down past my ass in the style many kids are rocking nowadays, except I don't rock the underwear or have the ass definition to pull off the look. Like an iPad, it's better placed in a bag. With everything else, really. Carrying stuff in your pockets is a pain in the arse and a great way to lose stuff.
Plus carrying a bag everywhere seems somewhat impractical. (Ok, most girls I know do carry a bag everywhere, most guys I know don't).
