I think the important question here is how do you pass time on the toilet?
I thought I was the last young holdout, getting a smartphone at the end of 2009. For most people nice to have, but not necessary, but if you want to justify the cost, think of it like this:
I use my smartphone a lot when I’m out shopping. At a store, should I buy this? Let’s check the price online, or let’s read the reviews. Saves me some money doing that for things I haven’t planned ahead for. Now it doesn’t save me the difference in the cost of the phone, but defiantly can aide you in making quick decisions.
While a lot of apps can be a big distraction, it also makes a lot of things more efficient. You get a quality camera/video recorder/flashlight/mp3 player/web browser/video player/gps/yellow pages all in one small device. Just about everything you do probably has an app (except maybe Celticsblog). Your bank, brokerage accounts, any magazines/newspapers you read, plus things like stock quotes and weather. Having all that stuff at your fingertips can definitely save you some time. So is the convenience worth it? I’m pretty cheap, but I don’t think I’d go back to a non-smartphone anytime soon. From a business perspective it helps to be able to get/send emails from anywhere at any time too. Not that I have to be by email 24/7, but once in a while there’s an important email you want to get/send right away, but might be delayed several hours while away from a computer.
Think of it like owning a car vs a bicycle or taking the train/bus. You might only live a few of miles from work, but most people would choose a 5-10 minute drive and the freedom to drive wherever they want whenever they want vs the 30-45 minute bike/bus ride and the lack of traveling independence. Sure the car’s more expensive, but most people think the added convenience is worth the extra expense. Oddly, I have a smartphone but no car, and don't live in a major city like NYC/Boston where not having a car is normal.
