Ever try using a computer in a car ride? Or on a busy street corner? Or a restaurant? Or anywhere that isn't your bedroom or starbucks? Yeah, computers are better from a performance standpoint, but functionality and versatility are today's noteworthy sellpoints.I'm never in that situation so I guess I can't relate. I still don't think accessibility is worth purchasing another device for though.
Also, have you ever tried taking a photo with your computer? Yeaaahhhhh.....
From a business standpoint, relying on a stationary device to communicate with others is about as sick a joke as possible. Even from my more menial labor-ish job, relying on a pc for my internet needs like email and business purchases is a waste. I can be essentially anywhere at any time and fire off an email, order something off the web, and still watch a funny video afterwards while sitting at a bus stop or train station. To be extremely fair, my galaxy s4 runs about as fast as a cheap pc anyway, so why would I bother owning a computer for functions my smartphone covers just as easily?
Btw,I used this exact conversation minus the galaxy s4 statement ( it was an infuse at the time), to sell phones while working in Radioshack. It worked 6 times. The times it failed were because the following credit checks for said customers qsked for 500 dollar deposits for accounts to be created. Fucking money.
