To their credit, the honchos behind this seem to recognize that people aren't going to sit there and stare into a tiny cell phone screen for two hours. According to a Sony exec, the objective isn't to get people to watch the whole movie, and they don't expect too many customers to watch Ghostbusters for the first time on a two-inch display. Rather, this is intended for those who've already seen the films and want to rewatch certain scenes on a whim.
Sony, of course, was responsible for the fleeting phenomenon of watching movies on your PSP (portable Playstation), and they don't seem to be giving up on "mobile entertainment." I guess there's been some traction; I have friends who keep up with their favorite TV shows on their commutes. My mind still boggles at the concept of this actually being a viable business model -- Don't your arms get tired? What do you even see in there? -- but I suppose people are starting to embrace anything they can carry with them on their gadgets. I'll leave you with David Lynch's immortal -- and entirely correct -- words on the subject, after the jump.
