We all know the frustration of spending heavily on a gadget only to see it become obsolete within what seems like minutes. And you might want to keep that in mind with the arrival of the Apple Watch this month, writes Christopher Mims in the Wall Street Journal. "Anyone who isn’t a self-described early adopter might want to avoid the entire category of wearables, at least for a few more years," Mims notes. That's because the products' development is set to "evolve at a breathtaking pace over the next two to five years."
Right now, there are all kinds of different smartwatches, all focusing on different answers to the question: "Which parts of a smartphone does it make sense to put on a person’s wrist?” Mims notes. The market will help decide what works. Meanwhile, the watches, which, as it stands, mostly depend on pairing with smartphones, are likely to become more workable as independent devices. But if you are one of those who has to have the Apple Watch as soon as possible, you'll need to take action soon, CNET reports. Sales require online reservations, at least for now: You won't be able to just hurry into an Apple Store the day it comes out. (And you might want to think twice about which model you buy.)
