If your thinking about buying a new gadget in the near future, you may want to take a look at what you’re already carrying around today. Chances are one of them is a cellphone or smartphone. You may have a second one work. Another device may be a laptop or tablet. The point is everyone believes they have what they need, even if that means carrying a sack full of gadgets everywhere they go.
The average person carries at least 1-2 gadgets with them. One of those devices is almost guaranteed to be a cellphone of some kind. The other depends on what the first device does and doesn’t do. Case in point: the iPhone. It can do everything except load a Flash-supported website. Also, it’s only got a 3-4″ screen. For web browsing and Flash, an Android tablet would be a nice way to fill that specific void.
A person’s career can also play a role in how many devices they need. Photographers prefer to have high-end cameras with a collection of lens instead of relying on the point-and-shoot features of their smartphone and/or tablet. It all depends on what you need or want to do.
Is there a limit to the number of gadgets one person should carry? No, but most prefer to have more than one with them. If you wish to carry the least amount of stuff possible, all you have to do is make a list of the features you need and work from there. Most people won’t have to buy more than two, but some do have a legitimate reason to carry around backpacks and bags full of gadgets.
Is there a reason not to buy certain gadgets? Yes, but only because they’re considered obsolete. Beyond that, the choice is up to you.
